Given a $0.1\,M$ solution of each of the following. Which solution has the lowest $pH$

A
$NaHS{O_4}$
B
$N{H_4}Cl$
✓
$HCl$
D
$N{H_3}$

✓

Answer

Correct option: C.

$HCl$

(c) Because it is a strong acid.

${H^ + } = {10^{ - 1}}$

$pH = - \log \,\,[{H^ + }]$ $ = - \log \,\,[{10^{ - 1}}]$; $pH = 1$.
