$p H \approx 3.08$

#### Explanation:

Recall that the formula for $p H$ is:

$\textcolor{b l u e}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} p H = - \log \left[{H}^{+}\right] \textcolor{w h i t e}{\frac{a}{a}} |}}}$

where:
$p H =$pH
$\left[{H}^{+}\right] =$concentration of hydrogen ion

Determining the pH
To find the pH, substitute your known values into the $p H$ formula and solve.

$p H = - \log \left[{H}^{+}\right]$

$p H = - \log \left(0.000841 M\right)$

$\textcolor{g r e e n}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} p H \approx 3.08 \textcolor{w h i t e}{\frac{a}{a}} |}}}$
