8.2.A—Calculate pH and pOH based on concentrations of all species in a solution of a strong acid or a strong base

[Maximum number: 1]

Answer the following questions about magnesium.

Calculate the pH of the solution in beaker 2.

C For the correct calculated value:

Point 05

$\begin{aligned} & \mathrm{pOH}=-\log \left(2.80 \times 10^{-4}\right)=3.553 \\ & \mathrm{pH}=14-\mathrm{pOH}=14-3.553=10.447 \end{aligned}$
