Year 8 Acids, Alkalis and Neutralisation Worksheet (with Mark Scheme)
A printable Year 8 (KS3) chemistry homework worksheet on acids, alkalis and neutralisation that builds strong GCSE foundations. Students practise key words and state symbols, the pH scale, litmus and universal indicator, ions, naming salts, and writing word equations for neutralisation, including reactions with metal carbonates. A challenge question introduces symbol and ionic equations. A full mark scheme with marking guidance is included.
