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 green precipitate (R) in an ammoniacal medical. The precipitate (R) gave a coloured solution (S), when treated with H_(2)O_(2) in an aqueous NaOH medium. Answer Question 62 and 63 The precipitate P contains

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_(2)S in a dilute mineral acid medium. However, it gave a green precipitate (R) in an ammoniacal medical. The precipitate (R) gave a coloured solution (S), when treated with H_(2)O_(2) in an aqueous NaOH medium. Answer Question 62 and 63 The precipitate P contains
Answer» <P>`Pb^(2+)` `Hg_(2)^(2+)` `AG^(+)` `Hg^(2+)` SOLUTION :The precipitate (P) contains `Pb^(2+)` IONS.
