IB DP Chemistry R3.1 L16 | Buffer Solutions: How They Resist pH Change | Lesson Walkthrough

Explain how buffer solutions resist pH changes when small amounts of acid or base are added.

Calculate buffer pH and composition using acid-base equilibrium relationships.

Interpret titration curves involving strong and weak acids and bases.

Explain acid-base indicators as weak-acid equilibria and relate colour to pH.

Write neutralisation reactions, identify spectator ions and explain salt formation.

Interpret strong acid-strong base titration curves and explain the sharp pH change near equivalence.

Calculate pOH and connect pH, pOH and acid-base concentrations.

Use Ka, Kb, pKa and pKb to quantify acid and base strength.

Relate conjugate acid and base strengths using Ka, Kb and Kw.

Predict the pH of salt solutions using hydrolysis and acid-base equilibria.
