IB DP Chemistry R3.1 L3 | Amphiprotic Species: Acting as Acid and Base | Lesson Walkthrough

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

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.

Predict equilibrium shifts caused by concentration, pressure and temperature changes and distinguish these from changes in K.

Calculate the reaction quotient and compare Q with K to predict the direction of net reaction.

Construct ICE tables and solve for equilibrium composition using exact algebraic methods.

Use and test small-K approximations, then solve mixed equilibrium-composition problems.
