Q: "work in progress" - hiding an answer which is being formulated.

MaxWIf I'm trying to put an answer together where should I do that? I'd guess answer the question but delete the answer. So the answer could still be worked on, but others wouldn't be bothered by trying to read a half-finished answer. Part of the problem is that I don't have any editor that will al...

Q: I am asking about chemistry, you know, that's why I put it in the title

Martin - マーチンPreviously on 'Never mind the Buzzwords': I question the use of "question" in question titles (search here) Help make help questions have more helpful titles (search here) Houston, we have a "Problem" in question titles (search here) Buzzwords in question titles - season 4 & 5 - experiments an...

Whoa, sure the chips is busy today.
Hey everyone :)
I assume that's me. Hullo!

The internet is so crappy today.

Help on Chemistryyy!
-_-
I can't even see the question on the main page, does having a score of -6 hide it or something?
Possibly, btw those titles are incredible sometimes

Q: Is PVC membrane roofing safe for health in use?

MyshkinI'm interested only in use aspect, not producing or utilization (for example, living on the last floor where PVC roof is used). There are two opposite opinions about this question. Manufacturers claims that PVC roofing is safe and refer to government research results that found PVC roofing comple...

This question for me seems "off topic"
@orthocresol -4 hides it from the main page.
BTW @Ortho @Jan I have an answer for you two to process and understand and see if it's another troll or not.
@Freddy Yes.

A: What is the process of turning ionic silver solution into colloidal silver solution?

KerryMy sister and brother-in-law have been making colloids for many years - Silver, Gold, Zinc and Copper. They use these themselves and also supply naturopaths. I should add that they are retired and enjoy excellent health. The equipment they used in making Ag colloid was three 9-volt batteries in ...

@Ortho ^
I don't know anything about silver colloids. But an answer that encourages ingestion of silver, as well as "sloshing it around in the mouth with DMSO", is questionable.
In the mouth?
Then first comment, and we judge their comments, and see if they're a troll.
Something like that, I didn't read it thoroughly.
Well, me neither, that's why I asked you guys. :P
Anyway just read it when you got the time.
19:01
Fwiw I don't think it's a troll, probably just a misguided soul.
Oh... It's not sloshing DMSO in the mouth... It's applying it to the skin.
Anyway, a quick Google search shows that the ingestion of colloidal silver is indeed pseudoscience.
Can we get these deleted?
@orthocresol These?
You mean the chat messages?
19:23
It is sloshing in mouth and should be deleted as propagating potentially dangerous pseudomedicine
> naturopaths
??
My prof keeps saying that the solubility of tin is one atom
Any sources to back this up?
He said that someone long ago experimentally determined this
@Dissenter One atom?!
Um, that's . . .
Let's go read some Wikipedia or something on it, and see how much he's wrong. :P
19:31
;)
The question is if we put some tin in water and one tin atom is solvated
And then we pour half the solution into another beaker
Which beaker has the tin atom?
@Ϻ.Λ.Ʀ. No, I meant these kind of answers.
@Dissenter Schrodinger's solution.
20:26
Hey all!
@Ϻ.Λ.Ʀ. hello codictator! ;)
@Ϻ.Λ.Ʀ. seems very quiet today! why?
@Ϻ.Λ.Ʀ. \o
@TanMath How would I know?
@Ϻ.Λ.Ʀ. what is your idea for the TRE episode 2?
How could I know?
20:28
@Ϻ.Λ.Ʀ. you are the codictator!
@TanMath Tag focus.
BTW I'm writing homework, you're disallowing me.
@Ϻ.Λ.Ʀ. oh, you are working on homework? okay, sorry!

Q: Chemical bonding- shapes of molecules

user282856I have been recently studying about all the types of bonds and hybridisation, VBT, VSEPR, MOT etc. But I am finding it difficult to draw the structure of different molecules and decide their geometry, so I need some helpful advice about how I can avoid getting confused in chemical bonding, or rat...

Too broad?
TOO broad.
@Ϻ.Λ.Ʀ. i thought you were doing HW?
@orthocresol oh yeah!
@TanMath I am.
@Ϻ.Λ.Ʀ. really? I guess along with that you are checking the chat?!
Yes. Shh.
20:59
@Ϻ.Λ.Ʀ. then let us chat secretly

I'm sorry but I wasn't sure really either FH2 + KO or H2O + FK not really sure actually — Ryan Henry 19 mins ago
@orthocresol what is he even writing?
I asked him to write the products of the reaction of HF with KOH.
I really am not trying to be condescending, I am not saying that he is stupid for not knowing it, I just wonder, why is he learning how to do acid-base equilibria calculations when he can't write a balanced equation for the reaction... ._______.
@orthocresol ok.. First of all, his first choice makes no sense! second of all, he can't even write a molecule formula correctly! it should be KF, not FK!
@orthocresol weird huh?
@TanMath well, I do not care much about whether it is KF or FK.. although obviously we are used to seeing KF... we do see the anion put first sometimes, such as in CH3COONa, and it is strictly speaking not wrong.. unless there is some IUPAC rule that I don't know of...
But H2F and KO... :/
@orthocresol but we write it like that to show what the Na is attached...
@orthocresol do such chemicals even exist?!
22:13
@TanMath Yeah, but if there was a rule that said cations have to come before anions, then we would write it NaOOCCH3 or something like that. That still shows you where the Na is attached to.
@TanMath No... not in aqueous solution at least...
@orthocresol but we are technically delving into organic chem, in which condensed structural formulas are used..
@orthocresol I bet KO would be the strongest base if it did exist...
[H2F]+ does exist, though. You can form it in concentrated HF.
@orthocresol i thought so...
@orthocresol IUPAC rule ≠ convention
@Ϻ.Λ.Ʀ. true.. many organic molecules are not called by their IUPAC name, like acetic acid...
22:22
That's not what I aimed at, but yeah.
@Ϻ.Λ.Ʀ. what did you aim at then?
BtW, you finished your homework? or are you again secretly checkng chat?
Nicolau knew these formula notation standards better than me.
@TanMath I haven't finished it, and I'm not secretly chatting.
@Ϻ.Λ.Ʀ. huh?
you have homework yet you are freely chatting?
@Ϻ.Λ.Ʀ. you are irresponsible!
22:27
A bit late for that in 2 a.m.
@Ϻ.Λ.Ʀ. As I asked, what is your idea for the next TRE?
@TanMath Note that "acetic acid" is the preferred IUPAC name and not "ethanoic acid".
@orthocresol really? I thought it was the other way around!
I can't access the 2013 recommendations, but Section P-65.1.1.1 of this provisional draft states that formic acid, acetic acid and benzoic acid are preferred IUPAC names.
@orthocresol That's still true according to the 2013 version.
22:42
@Loong Do you have a printed copy of it with you?
@orthocresol pdf
@Loong Ah, I see...
@TanMath IUPAC isn't that boring.
@TanMath Don't spoil the surprise. ಠ_ಠ
That pdf is so expensive to obtain legally, it's like £27 for one chapter -_-
