Question

arrange hydroxides of alkali metals in order of their acidity​

Answer 1

Explanation:

On moving down the group of alkali earth metals, the basic character of hydroxides increases from LiOH to CsOH. As the size of the metal cation increases, the internuclear distance betwen metal cation and the oxygen of the hydroxide group increases. This increases the ease of ionization of the hydroxide ion.

Answer 2

Explanation:

Basicity of hydroxides of alkali metals increases on descending the group.
