The salt which in solution gives a pale green precipitate with sodium hydroxide solution and a white precipitate with barium chloride solution is:
The correct option is B.
Iron(II) sulphate
Explanation:
When ferrous sulphate reacts with sodium hydroxide, a pale green precipitate of sodium hydroxide and sodium sulphate is formed.
FeSO4+2NaOH→Fe(OH)2+Na2SO4
When ferrous sulphate reacts with barium chloride, a white precipitate of barium sulphate is formed.
FeSO4+BaCl2→BaSO4+FeCl2
