Acid plus metal
An acid produces hydrogen ions when it dissolves in water. A reactive metal reacts with a suitable dilute, non-oxidizing acid, such as hydrochloric acid or sulfuric acid, to form a salt and hydrogen gas.
Step-by-step lessons covering AQA GCSE Chemistry 4.2.1 Reactions of acids with metals for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
