उत्तर
Ammonium sulphate on reacting with sodium hydroxide liberates ammonia gas:
\[\ce{NH4)2SO4(aq) + 2NaOH(I) -> Na2SO4(aq) + 2NH3(I) + 2H2O(I)}\]
Sodium sulphate on reacting with sodium hydroxide undergoes the following change:
\[\ce{NaOH + Na2SO4 -> NaOH + Na2SO4}\]
However the products would be the same as the reactants, therefore providing no observation for a visible chemical reaction.
