Aqueous solution of ferric chloride is

If $0.1 \, M \, CH_3COONa$ undergoes $1 \%$ hydrolysis,then the values of $[OH^{-}]$,$[H^{+}]$,and $pH$ are respectively:

$A$ weak acid $HX$ $(K_a = 10^{-5})$ on reaction with $NaOH$ gives $NaX$. For $0.1 \ M$ aqueous solution of $NaX$,the $\%$ hydrolysis is $....... \ \%$.

What is the $pH$ of $1 \, M \, NH_4Cl_{(aq)}$ at $25 \, ^\circ C$?

$A$ $100 \ mL$, $0.1 \ M$ solution of ammonium acetate is diluted by adding $100 \ mL$ of water. The pH of the resulting solution will be ($pK_{a}$ of acetic acid is nearly equal to $pK_{b}$ of $NH_{4}OH$)

The aqueous solution of copper sulfate is acidic because...
