Chlorides and Nitric acid
« on: 03/04/2006 16:43:50 »
When you add nitric acid in excess to a chloride solution you get chlorine.  Does any body know the mechanism for this process???

Do you mean chlorine the element?

Or chlorine as in chlorine bleach.  
(Not Really chlorine)=[(H-Cl-O) or Na+(ClO-)]

I think
HNO3 + Cl- --> NO2 + H-Cl-O

This is actually a redox reaction occuring in an acid solution. The mechanism for this reaction assuming that chlorine gas is a product... is this:

2HNO3(aq) + 2H+(aq) + 2Cl-(aq) -> 2NO2(g) + 2H2O(l) + Cl2(g)

Why would you want to make chlorine gas?  That stuff is toxic!
An easy way is to mix bleach and ammonia but you can end up with other things than Cl2 that are explosive![xx(]
DO NOT TRY TO MAKE CHLORINE THAT WAY!
