IB DP Chemistry R3.1 L1 | Brønsted-Lowry Acids and Bases: Proton Transfer | Lesson Walkthrough

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.

Use water equilibrium and the ion product Kw to relate hydrogen-ion and hydroxide-ion concentrations.

Compare strong and weak acids and bases through extent of ionisation and experimental evidence.

Explain dynamic equilibrium in a closed system and distinguish equal reaction rates from equal concentrations.

Write equilibrium constant expressions from balanced equations and use stoichiometric coefficients as powers.

Calculate equilibrium constants from composition data using careful concentration bookkeeping.

Interpret the magnitude of an equilibrium constant and explore how its value changes when the equation is transformed.
