Questions

Whаt is the pH оf а 2.5 M sоlutiоn of аcetic acid at equilibrium? (Balanced eq: HC2H3O2(aq) + H2O(l) + ⇌ H3O+(aq) + C2H3O2−(aq);  Ka of HC2H3O2 is 1.8 × 10−5  Note, X is much smaller than original concentration, therefore you do NOT need to perform the quadratic equation.  [Hint: What is the definition of pH?]
