Reaction: Br2(aq)+AgNO3
« on: December 01, 2014, 03:43:39 AM »
Is is possible? And what are the possible products?

I suggest Br2+AgNO3 :rarrow: AgBr :spindown:+BrNO3
What do you think?

Update: I still think it is highly unlikely to get BrNO3. Probably in aqueous solution the silver ions just shift the equilibrium of the bromine hydrolysis to form Br- and BrO3-:

Br2+AgNO3+H2:rarrow: AgBr :spindown: + HBrO3 + HNO3
or
Br2+AgNO3+H2:rarrow: AgBr :spindown: + HBrO + HNO3

Thoughts?

Bromine in water stay in an equilibrium what is almost on left side.

Br2 + H2O => HBr + HOBr

If you add silver ion you will shift it more to the right side.

AgBr will precipitate.

Thanks! I read that HOBr is very unstable in water at temperatures above 0 °C, it will disproportionate to bromate and bromide, so the products at normal conditions would likely be:
Br2+AgNO3+H2:rarrow: AgBr :spindown: + HBrO3 + HNO3

Equation is not balanced.
