Question

give reasons :-
(a) we can store copper sulphate solution in a silver vessel but not silver nitrate solution in a copper vessel.
(b) the reaction of Zinc with dilute nitric acid does not produce hydrogen gas

Answer 1

( a ) We store copper sulphate solution in a silver vessel because silver is less reactive than copper. So no displacement reaction occurs. Silver nitrate solution is not stored in copper vessel because copper is more reactive than silver.

( b ) The reaction with dilute nitric acid does not produce hydrogen gas because zinc is not a highly reactive metal.

HOPE THIS HELPS.................... :)

Answer 2

if we store silver nitrate solution in a copper vessel then copper being more reactive than silver displaces silver from it's salt solution which leads tarnishment of our silver vessel


because HNO3 is a strong oxidising agent.. so as soon as hydrogen gas is evolved HNO3 oxidized it and H2 convert into water
