Hydrolysis of sodium acetate will give:

An aqueous solution of aluminum chloride is acidic due to $........$.

Explain the following with reasons:
$(i)$ $NaCl$ solution is neutral. The solution of strong acid and strong base salts is neutral.
$(ii)$ $NaCH_3COO$ solution is basic. The solution of strong base and weak acid salt is basic.
$(iii)$ $NH_4Cl$ solution is acidic. The solution of weak base and strong acid salt is acidic.
$(iv)$ The solution of $NH_4CH_3COO$ is (almost) neutral. The solution of weak acid - weak base salts is almost neutral.

If the $pH$ of a solution is less than $7$,it will be ......

$A$ white substance having alkaline nature in solution is
