. Paragraph for Question Nos. (i) and (ii) An aqueous solution of a mixture of two inorganic salts, when treated with dilute HCl, gave a precipitate (P) and a filtrate (Q). The precipitate P was found to dissolve in hot water. The filtrate (Q) remained unchanged, when treated with H 2 S in a dilute mineral acid medium. However, it gave a precipitate (R) with H2S in an ammoniacal medium. The precipitate R gave a coloured solution (S), when treated with H 2 O 2 in an aqueous NaOH medium. (i) The precipitate P contains Hg 2+ (ii) The coloured solution S contains Na 2 CrO 4
