IB DP Chemistry R3.1 L11 | Conjugate Strengths and the Relationship Ka × Kb = Kw | Lesson Walkthrough

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

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

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.

Define Brønsted-Lowry acids and bases and identify proton transfer in reactions.

Identify conjugate acid-base pairs and track the changes in proton number and charge.

Explain amphiprotic behaviour and identify species that can both donate and accept protons.

Convert between pH and hydrogen-ion concentration and interpret the logarithmic pH scale.
