A: Deriving the equation for oxygen estimation by Winkler’s method

[Concepts] Normality, N: The normality is the relation between the sustance equivalence and the liters of a solution. The sustance equivalents are referred to the charges per mole of a sustance. The number of equivalents (NOE) of a sustance is obtained as follows: Acid equal to number of hydr...

$\uparrow$ Someone help this lost soul in fixing the MathJax using \textrm and writing the equations in mhchem.

Loong

@MAFIA36790 That's probably the least of the problems with this answer.

user116211

Haven't read it; it's bothering when you see such poor formatting.

Loong

Yes, I totally agree. And that could keep me from reading a text.

But in this case, it's not just typography.

The quantities in the equations are a mix of quantity symbols, quantity names, abbreviations, and unit symbols.

They are also mostly antiquated non-standard quantities ("normality", "weight equivalent gram", "weight equivalent number", "molarity").

And then suddenly a conversion factor of 1000 appears without any units.

@Loong Will you share in my hatred of Atkins?

Loong

@orthocresol ouch, yeah

@ortho @Loong A little assistance...where's the log out button?

(main site) ._.

I'm currently logged in via my Google account (if that helps)

Loong

@paracresol And you want to change that?

user116211

Atkins?

Loong

@paracresol You should be able to see it here: chemistry.stackexchange.com/users/mylogins/33991

user116211

@Loong Then it's a pretty hotch-potch; as I said, I didn't bother to go through it.

user116211

13:52

@orthocresol yes, he used it numerous times in his book.

Loong

@paracresol Or do you just want to clear your current session?

user116211

I'm not sure about any new edition or so.

paracresol

@Loong Yep...annoying little brother came over for Christmas and he's screwing around with my account (typing crap all over the site and such)... -_-

(I bet @Kau's gloating about this)

user116211

@paracresol Can't you let him use the browser in incognito mode/private window?

paracresol

@MAFIA36790 Ah no...he's hell bent on screwing up my account...it's not like he's doing this accidentally -_-

user116211

14:00

horror

paracresol

^ More like frustration ;)

Loong

@paracresol I can force you to be logged out. So you would have to manually log in again.

paracresol

By the way @Mafia would you know how to go about this log-out business?

@Loong How does that work?

(It sounds promising)

user116211

@paracresol Actually, I'm not accustomed to that; but it's pretty bothering.

paracresol

All eyes on Loong

Loong

14:02

@paracresol I would invalidate your browser cookies.

paracresol

@Loong That's just a one-time thing...right?

Loong

@paracresol Yes. In addition, you could change your password to be sure.

So, do you want me to try?

Where is your effort? Note that Chemistry.SE is not a homework solving service; do show some effort to work through the problem. — MAFIA36790 53 secs ago

user116211

$\uparrow$ After a long time, I did jot that down here.

user116211

How come there is no wikipedia article on Darryl Holm? ;(

orthocresol

14:17

@MAFIA36790 This is in Shriver & Atkins, 6th ed.

Neither Shriver nor Atkins are still authors. :)

user116211

@orthocresol We might have a copy or two in our university library; but am not sure.

user116211

Hey Jan!

orthocresol

Shriver passed away in 2013: onlinelibrary.wiley.com/doi/10.1002/anie.201306778/abstract and Atkins is in retirement.

user116211

ohh.

user116211

Wait, speaking of death, some experimentalist passed away recently.

user116211

14:22

Yes, Sidney Drell.

user116211

He is more of an experimentalist, I believe.

Jan

I always log out when I leave xD Even on my private laptop.

Cool I got a downvote. Only two more to go to win peer pressure =D

Loong

@Jan Oh yes, that seems to work. You have a lot of logout events in your user history.

user116211

@Jan I didn't downvote, btw. It's beyond my knowledge to judge the post ;)

Jan

@MAFIA36790 Rly? You don’t trust yourself determining oxidation states? O__O''

Loong

Er, is it really such a good idea to mention a 2 % KCN solution for cleaning mold on

user116211

Wait, I know these, oops.

user116211

I didn't even bother to try what topics the posts there were talking about.

Depending on the environment this is happening in (pets, children, food preparation, ...) this permanent solution might not apply. A bit of back-ground: Mould is one of the oldest life forms on Earth and thus pretty resistant to pretty much everything... You can temporarily stop growth, but ev...

user116211

I'm just not interested.

Jan

@Loong It can definitely serve as a Darwinistic separator.

Loong

> a gas smelling of nice raw almonds

This can be dangerously misleading.

user116211

@Loong wow! He smelt it.

Jan

Tell people to use it and thereby remove those from the gene pool who are too stupid …

Loong

@Jan or those who cannot smell it

Jan

I don’t see any mention of adding acid, though …

user116211

Uff; for so long, I've been searching to vote to reopen some posts; but god damn, all I can do is Leave closed; I won't get that hat ever ;(

Jan

14:39

I was surprised that I got 180° just by editing and voting to reopen. But then later the community sided with me (just) and I also got the no longer grinchy =D

Closing in on @Loong’s hat collection! x3

user116211

Elementary Hat is the best so far.

Jan

> Elementary, my dear @Mafia

user116211

;)

Jan

Awww, damn it. It’s sticking at one downvote =C

Loong

Are you asking for more downvotes?

Jan

14:44

Well I either need upvotes on the post so I can come closer to rep capping today again (and thereby adding a hat to my collection) or I need two more downvotes to win a badge. Whichever seems easier ;)

orthocresol

@Jan You already have more hats than Loong, don't you?

Jan

Last time I checked I didn’t.

orthocresol

You have 16, Loong has 15 - or are you only counting those on Chemistry? Haha

I've gotta try harder.

Jan

winterbash2016.stackexchange.com/leaderboard/…

You’re good at secret hats.

orthocresol

I have no clue how I do it.

I want to have the hatter. It’s such a beautiful hat.

10 upvotes?

user116211

On question or answer?

user116211

Or on comment?

user116211

Suspense? ;(

orthocresol

Maybe it has to do with getting a Nice Answer badge.

Actually, no; the only Nice Answer badges I received were on meta.

user116211

Chester Miller didn't get the hat in spite of getting 13 upvotes in his answer.

user116211

14:57

@orthocresol Ahh!

Jan

I think, the doc linked in the hat thread suggests something with comments.

Loong

It should be easy to get The Hatter.

user116211

stares at Loong

Jan

I’m guessing the Hatter is this year’s It’s Always 5 O’Clock Somewhere?

Loong

@Jan yes. Ask at HH:00 or HH:15.

user116211

14:59

@Jan What was that for? I couldn't remember.

Jan

Any day?

Loong

@Jan Apparently, yes.

user116211

UTC, right?

orthocresol

The doc seems to suggest so.

Jan

Last time I checked they were on about the fourth or the sixth day of a week …

And I would have thought it has something to do with Alice through the Looking Glass and the tea party with Time therein …

But the doc still states the wrong condition for This is Fine so …

orthocresol

Yes, they don't seem to have noticed your comment on the meta.SE post.

Neither did they notice my post in the Hat Shoppe.

user116211

It's sometimes quite annoying when one asks that even though OP is reading such text that assumes he/she knows that or have already prepared the required background.

Jan

@MAFIA36790 Do telephones still have operators that you would get?

user116211

;P

Loong

15:09

@Jan $☎$?

user116211

I assume OP is talking about how the term with the nabla operator came in that context; I've explained that already in my post; hopes he/she reads that.

user116211

Any of you watched the Rogue One?

user116211

yet?

user116211

Or future plan?

orthocresol

This user happened to get a gold badge (and hence the hat 24) during Winterbash: chemistry.stackexchange.com/questions/7449/…

This one, too: chemistry.stackexchange.com/questions/6780/…

As far as I can tell, only Zhe and myself have Blue in the Face. Time to investigate...

user116211

15:18

@ortho, you forgot me.

user116211

I happened to get a gold badge from nowhere ;)

orthocresol

You got that on Physics. I'm talking about Chemistry ;)

I don't know when I will ever get a gold badge.

user116211

@orthocresol Yes.

user116211

I just need to get a silver badge now.

Jan

@orthocresol Fixed. xD

Loong

:-D

orthocresol

15:45

Hahaha :D

Jan

And that precisely is why I hate ‘intelligent’ systems.

Loong

@orthocresol The lab where I made my diploma thesis was connected to a "neutralizer" that looked like a small indoor swimming pool.

On that scale, the heat of neutralization was interesting.

And in the hot lab, you could even pour radioactive solutions down the drain.

I could hardly bring myself to do it.

orthocresol

That sounds dangerous ಠ_ಠ

user116211

I know Loong was working for Skynet.

orthocresol

@Jan, do you want a secret hat?

Jan

Always! =O

orthocresol

Ok, don't do anything for the next 10 minutes, and I will test out my theory. If I am right, you will get a secret hat ;D

Jan

I just posted an answer xD

@Jan You should write an answer, and end it with "And thanks for aceept my answer".

Jan

@orthocresol It would fit perfectly onto my avatar on German Language, I think =D

user116211

16:08

@Jan Want to hammer it for no research efforts.

user116211

Mart has some interesting hats too.

orthocresol

16:21

Hmm.... That didn't seem to work.

user116211

:(

Jan

What was your attempt?

orthocresol

in Ye Olde Hat Shoppe, 14 mins ago, by orthocresol

I can (almost) confirm that Blue in the Face requires 10 distinct upvoted comments during the Winterbash period. Number of upvotes doesn't matter.

My backup theory is that "Possible duplicate of..." comments don't count. You have two such comments, so I just tried giving two more upvotes.

Jan

Wait, you just said that … ^^'

orthocresol

Enjoy your hat!

Jan

16:28

It worked! <3

user116211

So, what I need to get done? Get 10 distinct votes in my Possible duplicate of comments?

Jan

To make a random guess, the following type of comment probably would’t count either:

> I’m voting to close this question as off-topic because I’m in a good mood today.

@orthocresol (づ｡◕‿‿◕｡)づ

Loong

> I’m voting to close this question as off-topic because I could get a hat for that.

I should try that on the next homework question xD

Jan

16:35

Fun fact: Blue in the Face is even more common than Fiery xD

user116211

I need bad posts now.

Jan

I need two and a half upvotes. Upvote and accept is also fine.

user116211

Hmm, though in delay, Yoda hat, I got that.

orthocresol

@Loong I'll test the duplicate comment not counting thing again with Klaus.

He conveniently has 9 normal comments and 1 dupe comment since Dec 19. If he doesn't get the hat soon, it means that dupe comments don't work.

Jan

How convenient xD

@Loong Was it you who edited the Google doc? Why did you not kick out the bit on ‘answer must be posted after the start of Winterbash’? ;)

Loong

16:47

@Jan No I didn't edit that thing.

I took a look at some old questions and noticed that some \ce{} expressions were not working as they should. I am especially interested in how to write polyatomic ions. The old way results in numbers that are out of phase. According to these pointers \ce{CrO4^2-} should work. $$\ce{CrO4^2-}$$ A...

support mhchem formatting

Loong

@1,3-feeds My prediction has come true.

> With the current version of the mhchem extension of MathJax, the described workaround is no longer necessary. However, now the opposite workaround might become necessary in order to write a conforming formula such as $\mathrm{SO_4^{2-}}$ instead of the nonconforming version $\mathrm{SO_4{}^{2-}}$.

I almost forgot why I hate these unsolicited changes to MathJax/mhchem.

Jan

22:51

I didn’t know the community user was using an app =O

Loong

23:22

Yes, Community is currently answering the red phone for us.

Maybe we change it to something else if Community gets another interesting hat.

I still don’t get how community can be voting per app xD
