Vedclass · Answer

(D) The salt contains the $SO_4^{2-}$ anion. When a salt containing the $SO_4^{2-}$ group is treated with $H_2SO_4$ (dilute or concentrated),no reaction occurs because the common ion effect prevents the reaction,and $H_2SO_4$ is the acid corresponding to the sulfate radical. Nitrate,sulphide,and oxalate salts would react with $H_2SO_4$ to evolve gases like $NO_2$,$H_2S$,or $CO/CO_2$ respectively.
