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
Correct answer is B
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.
