$p H = 1.63$ $pH = 1.63$

Concentration of HCl is $0.0235$ $0.0235$ $M$ $M$

$[H C l] = 0.0235$ $[HCl] = 0.0235$ $m o l$ $mol$ / $L$ $L$

as $H C l$ $HCl$ is a strong acid, it will completely dissociate and produce $H^{+}$ $H^+$ ions.

[ $H^{+}$ $H^+$ ] = $0.0235$ $0.0235$ $m o l$ $mol$ / $L$ $L$

pH = $- log$ $-log$ [ $H^{+}$ $H^+$ ]

$p H = - log [0.0235]$ $pH = - log [0.0235]$

$p H = - (- 1.628)$ $pH = -(-1.628)$

$p H = 1.63$ $pH = 1.63$
