Which of the following has the highest solubility product?

Question

Which of the following has the highest solubility product? (A)  KOH  (B)  CsOH  (C)  LiOH  (D)  RbOH

Tardigrade Admin · Accepted Answer

On moving downward as the size of alkali metals increases, the solubility of their hydroxides increases. Hence, CsOH is highly soluble and hence, has the highest solubility product among the alkali metal hydroxides.

Q. Which of the following has the highest solubility product?

$K O H$

$C s O H$

$L i O H$

$R b O H$

On moving downward as the size of alkali metals increases, the solubility of their hydroxides increases. Hence, $C s O H$ is highly soluble and hence, has the highest solubility product among the alkali metal hydroxides.
