Weak Acid Titration Curve and pH Stages

Weak acid titration with a strong base changes pH in clear stages. The acid in this example is acetic acid, and the base is sodium hydroxide. Each stage uses a different pH calculation method.

At the start, the pH of the weak acid is found with its dissociation constant, Ka, and an ICE table. An ...

Titration calculations for weak acids and strong bases involve different approaches, depending on the primary reactant.

Initially, 50 mL of 0.1 M acetic acid has a pH of 2.87, calculated with the K_a and an ICE table.

Post titration with 0.1 M NaOH, the solution forms a buffer.

Adding 10 mL of NaOH creates...
