You have 500.0 mL of a buffer solution containing 0.30 M acetic acid (CH3COOH) and 0.20 M sodium acetate (CH3COONa). What will the pH of this solution be after the addition of 20.0 mL of 1.00 M NaOH solution?  [Ka(CH3COOH) = 1.8 × 10–5]

What is the pH of a 0.014 M Ca(OH)2 solution?

In the reaction, HSO4–(aq) + OH–(aq) SO42–(aq) + H2O(l), the conjugate acid-base pairs are                             pair 1             pair 2

Suppose 50.0 mL of a 0.100 M solution of the weak acid HA is titrated with a 0.100 M solution of NaOH. Which diagram best represents the equilibrium composition of the solution once 25.0 mL of titrant have been added? (Solvent water molecules are omitted for clarity.)
