Chapter 16, Problem 16.108SP

Like sulfuric acid, selenic acid ${\text{(H}}_{\text{2}}{\text{SeO}}_{\text{4}}\text{)}$ is a diprotic acid that has a very large value of ${\text{K}}_{\text{a}}\text{1}$ . Calculate the pH and the concentrations of all species present in 0.50 M ${\text{H}}_{\text{2}}{\text{SeO}}_{\text{4}}{\text{ (Ka}}_{\text{2}}=1.2\times {10}^{-2}).$
