Quizplus · Accepted Answer

Without knowing the pKa values of the two compounds, it is difficult to calculate the exact pH of the solution. However, based on the concentration of the compounds, it can be assumed that the solution is basic. Among the given choices, the pH closest to what would be expected for a basic solution is B, which is 9.70. Therefore, B is the best choice.
