Answer» The correct option is (d) (B), (C) and (D). • Sodium sulphate chemically reacts with barium chloride in the form of their aqueous solution to form a white precipitate of barium sulphate. • This is a double displacement reaction in which sulphate ions are displaced by chloride ions and vice-versa. |
