A. What is the pH of pure water?
B. What concentration of hydronium ions does a solution of pH 8 contain?
C. Complete the following reaction:
CH3COOH + H2O ? __________.
D. Will the reaction in (C) occur more readily (be driven to the right) if the pH of the solution is high?
A. pH 7
B. 10–8 M
C. CH3COO– + H3O+
D. Yes. If the pH is high, then the concentration of hydronium ions will be low. Therefore the rightward reaction, which produces hydronium ions, will be favored.
