Chemical changes case 051 reactivity-evidence. A student uses the reactivity series to justify an observation. Which option is best? Focus on neutralisation the reaction between acid and base alkali in Neutralisation of acids and salt production, not on a neighbouring Unit 4.4 reaction idea.
- A.Chemical changes case 051 reactivity-evidence: Uses the relative reactivity order to predict the change for neutralisation the reaction between acid and base alkali
- B.Chemical changes case 051 reactivity-evidence: Chooses the product by memorising a colour instead of the series (Neutralisation of acids and salt production)
- C.Chemical changes case 051 reactivity-evidence: Says any metal can displace any other metal ion (neutralisation the reaction between acid and base alkali)
- D.Chemical changes case 051 reactivity-evidence: Ignores whether the reacting substance is more or less reactive (Reactions of acids)
