An aqueous solution of a mixture of two inorganic salts, when treated with dilute

H C l

, gave a precipitate (P) and filtrate (Q). The precipitate P was found to dissolve in hot water.

The filtrate (Q) remained unchanged, when treated with

H_{2} S

in 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 coloured solution S contains:

$F e_{2} (S O_{4})_{2}$
$C u S O_{4}$
$Z n S O_{3}$
$N a_{2} C r O_{4}$
