The reaction question thread.
I thought it would be nice to have a thread where people can ask how does ******** react with ********. So I'll start off.
NaNH2+PH3==>NaPH2+NH3?
2Na+2PH3==>2NaPH2+H2?
3NaNO3+AsCl3==>As(NO3)3+3NaCl?

Many reactions are possible but another question is under what conditions.
For example hydrogen and ammonia looks simple on paper until you see actual pressure and heat required.

Yeah it would be nice if people added in under what conditions they react, but this is just a question of how a reaction proceeds.

I was wondering if barium nitrate could react with potassium perchlorate to make barium perchlorate and potassium nitrate.
Solubility of perchlorate is 66.48 g/100 mL (25 °C), While potassium perchlorate is only 1.5 g/100 mL (25 °C).
I think it wont work actually, just looking at the solubility data.
Can anyone provide a professional opinion on the subject?

Indeed the poor solubility of potassium perchlorate indicates that the equilibrium highly favors KClO4 over Ba(ClO4)2. Potassium perchlorate is kind
of a dead end for making other perchlorates. Sodium perchlorate or would be a better option, however if the intended use is pyrotechnic applications
removing all the sodium ions could be very difficult. I would start with ammonium perchlorate, although it is more expensive.

Ammonium perchlorate is generally made from perchloric acid.

No, I'll be using it to make perchloric acid, according to this reaction: Ba(ClO4)2 (aq) + H2SO4-->
BaSO4 (s) + HClO4 (aq).
I guess I can find another method to make barium chlorate.

It should. Phosphine will be a stronger acid than ammonia. Nasty stuff to work with, though.
Quote: | 2Na+2PH3==>2NaPH2+H2? |
It should. I know that triphenylphosphine will react with sodium to give NaPPh2 and NaPh (which was protonated under the reaction conditions, but I
don't recall what they were).

I doubt it. The arsenic-chlorine bond has significant covalent character, and I wouldn't expect the nitrate to bond as strongly.
