An aqueous solution of strong monoacidic base is of $1 \times 10^{-4} \mathrm{M}$. What is the value of pH at $25^{\circ} \mathrm{C} \cdot$ ?
- 7
- 4
- 3
- 10
Solution
$\begin{aligned} \mathrm{pOH} & =-\log _{10}\left[\mathrm{OH}^{-}\right] \\ & =-\log _{10}\left(1 \times 10^{-4}\right)=-(-4)=4 \\ \therefore \quad \mathrm{pH} & =14-\mathrm{pOH}=14-4=10\end{aligned}$
