Title: Reaction: Br2(aq)+AgNO3
Post by: unsu 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+H₂O  :rarrow: AgBr :spindown: + HBrO₃ + HNO₃
or
Br₂+AgNO₃+H₂O  :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+H₂O  :rarrow: AgBr :spindown: + HBrO₃ + HNO3

Equation is not balanced.
