Question

A white powder solid A forms a light green solution with water, which on treatment with potassium hexacyanoferrate(III) gives a blue precipitate. On being strongly heated, A leaves a
brown residue and forms a mixture of two gaseous oxides, which turns a dichromate solution
green and forms a white precipitate with a $B a C l_{2}$ solution containing concentrated HCl. A is:

Solution

The correct option is D $F e S O_{4}$
A: $F e S O_{4} \to F e_{2} O_{3} + S O_{2} + S O_{3}$ and with potassium hexacyanoferrate(III) it gives blue precipitate of ferro hexacyanoferrate(III).
