Which anion will form a precipitate with Cs^+? Cl^- SO_4^2- C_2H_3O_2^- s^2- none

Explanation / Answer

12. A SrSO4

Solubility of sulphates of alkaline earth metal are lower than those of alkali metal. Also the solublity of group-2 sulphate decrease down the group.

13. D AgBr

Halides of silver are water insoluble.
