Answer» 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 $H_{2} S$ in an ammoniacal medium. The precipitate R gave a coloured solution (S) when treated with $H_{2} O_{2}$ in an aqueous NaOH medium. The precipitate P contains
