Q. The solubility of alkali metal hydroxide is
A) $LiOH < KOH < NaOH < RbOH < CsOH$
B) $LiOH < NaOH < KOH < RbOH < CsOH$
C) $CsOH < RbOH < KOH < NaOH < LiOH$
D) None of the above
Explanation
(b)
The solubility of alkali metal hydroxides increases from top to bottom. Hence, the order of their solubility is as
$\ \ \ \ \ \ \ \ \ LiOH < NaOH < KOH < RbOH < CsOH$
