Reactions with Acid
Chemistry: AQA GCSE Higher, topic 4.2.5
Reactions of Metals with Dilute Acids
Most metals react with dilute acids to give a salt (e.g. aluminium chloride) and hydrogen gas.
Metals that do react with dilute acids
- Metals don't have to be that reactive to react with dilute acids.
- The metals that react with dilute acids but not cold water are magnesium, aluminium, zinc, iron and lead (iron and lead react slowly).
Metals that don't react with dilute acids
- The only metals that aren't reactive enough are copper, silver, gold and platinum.
