JEE AdvancedChemistrySalt AnalysisMCQ+3 / −1

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_2S

in a dilute mineral acid medium. However, it gave a precipitate (R) with

H_2S

in an ammoniacal medium. The precipitate R gave a coloured solution (S), when treated with

H_2O_2

in an aqueous

NaOH

medium.The coloured solution S contains

A
$F{e_2}{(S{O_4})_3}$
B
$CuS{O_4}$
C
$ZnS{O_4}$
D
$N{a_2}Cr{O_4}$
