The correct increasing order of $pH$ of $0.1 M$ solution of the following salts/acids is:

Answer:

Solution:

Let's analyse the nature of the given compounds:

Compound	Type of compound	Nature/pH
$HCl$	Strong acid	Strongly Acidic $\begin{matrix} pH = - \log [H^{+}] \\ pH = - \log 10^{- 1} \\ pH = 1 \end{matrix}$
${NH}_{4} Cl$	Salt of a strong acid $(HCl)$ and a weak base $({NH}_{4} OH)$	Acidic $(pH < 7)$
$NaCl$	Salt of a strong acid $(HCl)$ and a strong base $(NaOH)$	Neutral $(pH = 7)$
$NaCN$	Salt of a weak acid $(HCN)$ and a strong base $(NaOH)$	Basic $(pH > 7)$
