What is the $pH$ of an aqueous solution of sodium acetate?

The aqueous solution of $AlCl_3$ is acidic due to the hydrolysis of

Assertion $: -$ The aqueous solution of $Na_3PO_4$ is basic in nature.
Reason $: -$ $Na_3PO_4$ in its aqueous solution undergoes anionic hydrolysis.

For a weak acid $HX$ with $K_a = 1 \times 10^{-5}$,the reaction with $NaOH$ gives $NaX$. What is the percentage of hydrolysis $(\% \, h)$ for a $0.1 \, M$ aqueous solution of $NaX$?

In the hydrolysis of a salt of a weak acid and a strong base,$A^{-} + H_{2}O \rightleftharpoons HA + OH^{-}$,the hydrolysis constant $(K_{h})$ is equal to...

Assertion : $A$ solution of $FeCl_3$ in water produces brown precipitate on standing.
Reason : Hydrolysis of $FeCl_3$ takes place in water.
