Which of these solutions will give a white precipitate with a solution of barium chloride acidified with hydrochloric acid?
- Sodium trioxocarbonate (IV)
-
Sodium tetraoxosulphate (IV)
- Sodium trioxosulphate (IV)
- Sodium sulphide
The correct answer is: B
Explanation
The characteristic test for any soluble tetraoxosulphate(VI) is the formation of white precipitate (barium sulphate) when a solution of barium chloride, acidified with dilute HCl, or when a solution of barium nitrate, acidified with dilute nitric acid is reacted with it.
