A-Level Chemistry Lessons - April, 2026

We’ll explore entropy, including factors affecting it such as moles and physical states, and how to use Gibbs free energy to predict reaction feasibility. The focus will be on interpreting graphs and tackling the most challenging exam questions with confidence.

We’ll cover redox and electrode potentials, including half-cell theory, drawing solid, liquid, and gas half-cells, and hydrogen half-cells. The session will also explore electrochemical cells, redox equations, batteries, and fuel cells, with a focus on applying these concepts to the most challenging exam questions.

We’ll explore transition metals, including the distinction between d-block elements and true transition metals, exceptions, and key properties. The session will also cover complex ions, drawing them, precipitation reactions with their characteristic colours, and ligand substitution reactions, with a focus on tackling the most challenging exam questions.

We’ll analyse redox titrations, including titration technique, the manganese–iron reaction, and the iodine–sodium thiosulfate reaction, with a focus on applying these concepts to the most challenging exam questions.
