3 Full Lesson Bundle on Buffer Solutions. This bundle covers the AQA A Level Chemistry specification. Please review the learning objectives below. **Part 1: Explaining How Buffer Solutions Work To know a buffer solution is a system that minimises pH changes on addition of small amounts of an acid or base To describe how a buffer solution is formed using weak acids, salts and weak bases To explain qualitatively the action of acidic and basic buffers **Part 2: Buffer Solution Calculations (Part 1) To calculate the pH of a buffer solution containing a weak acid and the salt of a weak acid by using the Ka expression and pH equation To calculate equilibrium concentrations, moles or mass of the components of a weak acid-salt of a weak acid buffer solution Part 3: Buffer Solution Calculations (Part 2) To calculate changes in pH when a small amount of acid or alkali is added to an acidic buffer solution Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons including using your own lesson PowerPoints is a fundamental skill of a qualified/unqualified teacher that will be reviewed during these scenarios outlined above
