What does the hydrolysis of $AlCl_{3}$ produce?

Identify from the following salts an example of a salt of a strong acid and a weak base.

Do you expect different products in solution when aluminium $(III)$ chloride and potassium chloride are treated separately with $(i)$ normal water,$(ii)$ acidified water,and $(iii)$ alkaline water? Write equations wherever necessary.

If the $K_b$ value in the hydrolysis reaction $B^{+} + H_2O \rightleftharpoons BOH + H^{+}$ is $1.0 \times 10^{-6}$,then the hydrolysis constant of the salt would be

$A$ salt $'X'$ is soluble in water and has a $pH = 7$. However,the resulting solution exhibits alkaline properties. Then the salt is formed from -

Which salt represents the highest degree of hydrolysis?
