Below is a titration curve for the titration of 50.0 mL of a 0.100 M solution of the weak acid HA with a 0.100 M solution of NaOH.     What is the approximate pKa of HA?

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.)

What is the name of a proton acceptor in an acid-base reaction?

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?
