$p H = 1.344$ $pH = 1.344$

Hydrochloric acid is a stong acid, it fully ionizes to produce the hydronium ion and the chloride ion.

$H C l \to H^{+} + C l^{-}$ $HCl -> H^+ + Cl^-$

So, $[H^{+}] = [H C l]$ $[H^+] = [HCl]$ as a result of the complete ionization.

$[H^+] = 0.0453 \ M$

$pH = - log (0.0453)$

$pH = 1.344$
