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 precipitate P contains

A
$Pb^{2+}$
B
Hg ${}_2^{2 + }$
C
$Ag^+$
D
$Hg^{2+}$
