@IͶΔ It might be better to forget about it entirely. Just pretend it's soluble in nitrogen.

I flagged a post for spam and my flag was declined, yet that post was removed...

@NA It was no spam, it was offensive. In order to not confuse the automatic spam detection I had to decline it. See also here

I wonder if there is a way to know beforehand that what the products will be.

I knew your sentence would start with "I wonder ..." ;)

I would have never guessed the products in this reaction. (0:

@pH13 Chemistry is a wonderful science. (0:

touché

Maybe one should just memorize reactions like these, and there will be some explanation further in the texbook.

What is you chapter about?

@NA Spam != offensive

Well, @Mart always makes sense when it's not past midnight there.

@CopperKettle You don't need to memorize anything for science. Stamp collecting is another matter.

hmmm... I think I can make sense after midnight here. Just don't get me wet...

@pH13 Dissociation of salts

Dissociation of Zn(NO3)2 yields an acidic medium. But wait, we've got two ions of NO3(-) created in the process, would they not nullify the influence of ZnOH(+) and H(+)?

Zn(2+)+2NO3(-) + OH(-) + H(+) == ZnOH(+) + 2NO3(-) + H(+)

This is supposed to explain why the solution turns acidic.

But why not scratch out H(+), since this ion existed on the left side of the equation.

HOH = H(+) + OH(-)

Good afternoon, Muhammad!

@CopperKettle Afternoon

@CopperKettle What?

@IͶΔ The H(+) ion existed on the left too. Why not scratch it out, since they scratched out 2NO3(-).

Still I don't get why the solution is acidic. We've got two positive ions, and two negative.

@CopperKettle Are all these reactions happening in the solution right now?

Sorry, I'm a bit distracted.

@IͶΔ Yes, it's basically a simple reaction of dissociation of zinc nitrate

I asked a question on Socratic, since there's no downvotes there. (0:

Well, ZnOH+ is an acid, no?

Yes, it must be, since it wants to grab an electron.

So you have lotsa acid and not lotsa base.

But I've got 2 base ions of NO3(-)

two positives, two negatives, voila! zero net charge.

I'd better ask this on a Russian website too.

@Martin-マーチン Thanks for the clarification on that. I'm a moderator on another website and that's the kind of thing we would consider spam there, but I guess things are done differently around here :)

*The clarification about the flagging I mean

no problem

@NA Welcome to the Table anyway!

It seems that there's an error in the charges of PO4 here, they go from -1 to -2 instead of the other way.

Or maybe I don't understand something.

@IͶΔ A Russian chemist explained it in another way. What we obtain is a basic salt, Zn(OH)NO3, and an acid, HNO3. Hence the solution is acidic.

Probably because a basic salt does not dissociate and loses no OH(-) groups into the solution?

I forgot. Why when an acid loses H+ into the solution, why does the solution turn acidic? There's the negatively charged moiety too, generated by the same fact of H+ being split off. Why this negatively charged thing does not nullify the action of H+?

Can an 2NO3(-) ion make the medium more 'basic'?

A person answered my question on a Russian forum and said that it is only OH(-) ions that can make the medium 'basic'.

@CopperKettle No, because HNO3 is a strong acid and basic salts are usually weak.

I mean in their basicity.

@user36790 You mean why for instance, in Ca, the other 4s electron isn't contributing in the screening constant?

@IͶΔ But 2NO3(-) is a base, not an acid. It has not H(+) attached. Good evening, Mar.

Probably I should ask this on the main site and get a handful of downvotes.

@CopperKettle there are some errors

Yes, that answers volume is riddled with errors. I'll plow through it and switch to a better book at a higher level. (0:

you see that I was referring to the h3po4-image?

@pH13 Yes, the multi-stage salt lysis.

They got some numbers mixed up.

I'll go and read me some more.

BBL!

bbl?

@pH13 Be Back Later

@CopperKettle Yes, I agree.

@user36790 I know, I wanted to know what you know.

@user36790 But it wouldn't make sense if they did.

@Feeds What the hell

Why are people maining the meta?

I finally got some answers to my question, and they are great, very detailed

@CopperKettle Yay

@Feeds Huh, that feels good.

I should write more comments like that.

What really obtains when we react zinc with sulfuric acid?

1. Zn + H2SO4 → ZnSO4 + H2

2. 4Zn + 5H2SO4 = H2S + 4ZnSO4 + 4H2O

And this is a third(!) variation. O_o

Almost 90% questions in the first 2 pages are on hold!!

Homework questions, probably.

I wonder if my question just above is fit for the main site.

I asked it on Socratic, however, already
