Give reason for the following :
(a) Silver nitrate solution is kept in coloured bottles.
(b) Molybdenum is used in the manufacture of ammonia.
(c) Blue solution of copper sulphate changes to green when a piece of iron is added to this solution.

(a) The silver nitrate reacts with atmospheric energy provided by sunlight if kept in a transparent bottle and gets decomposed to silver oxide Ag2O so, the silver nitrate is kept in a coloured bottle.
(b) Molybdenum is used in the manufacture of ammonium because molybdenum acts as a promoter which increases the efficiency of the catalyst Iron, resulting in the better yield of ammonia.
(c) when an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is light green in colour. It is because iron is more reactive than copper.
