Question

To what colour does silver chloride changes when exposed to sunlight?

Answer 1

Hi Mate,

              I can give u the answer with some extra info too. See the reaction below :-

            2AgCl(s) → 2Ag(s) + Cl2(g)
           (white)    (black
                          or grey)

This reaction is a decomposition reaction caused by sunlight and so the name Photodecomposition reaction . When AgCl which is white, is exposed to sunlight, it decomposes into silver which is grey with a yellowish green gas which is chlorine.

     Hope this helps you .!!!!!
