Explanation:
When NaOH is added to ferrous ammonium sulphate solution and warmed, both ferrous ion and ammonium ion separate and exhibit their individual properties.
A green precipitate of Fe(OH)2 is formed and the smell of NH3 gas from (NH4)+ ion is observed.
Hence, it is an example of the formation of a double salt.
