Distinguish between the following :-

(a) Ammonium chloride and sodium chloride

➜ NH4Cl on strong heating sublimes to form dense white fumes which condense to white powdery mass on cooler parts of the tube whereas no white fumes on heating NaCl.

(b) Ferric salt and ferrous salt

➜ When ammonium hydroxide is added drop wise to solution to be tested. Ferrous salt gives dirty green ppt. Ferric salt gives reddish brown ppt of their hydroxides.

(c) Sodium sulphate and ammonium sulphate

➜ (NH4)2SO4 on warming with NaOH sol. gives NH3 gas. Sodium sulphate does not liberate NH3 gas.
