# What is the pH of a 0.0453 M HCl solution?

Jul 14, 2016

$p H = 1.344$

#### Explanation:

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

$H C l \to {H}^{+} + C {l}^{-}$

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

$\left[{H}^{+}\right] = 0.0453 \setminus M$

$p H = - \log \left(0.0453\right)$

$p H = 1.344$
