CAIE IGCSE Chemistry Acids with Metals Bases and Carbonates
Cambridge IGCSE Chemistry 0620 syllabus for exams in 2026, 2027 and 20282026–2028

Practise predicting acid reactions with metals, bases and carbonates, writing balanced equations and matching gas, dissolution or colour observations.

How this is tested

  • predict salt and hydrogen for a typical acid-metal reaction and describe effervescence
  • predict salt and water for neutralisation with a base and identify when excess solid remains
  • predict salt, water and carbon dioxide for carbonates and use fizzing as gas evidence

A

B

Hydrogen is produced when sodium hydroxide reacts with hydrochloric acid.

C

Methyl orange turns yellow in strong hydrochloric acid.
