Common mistake
Misunderstanding reactivity series relevance
Students think all metals will react with dilute acids, ignoring the reactivity series and the fact that metals below hydrogen (e.g., zinc, iron) may not react readily with dilute acids.
Explain that only metals higher than hydrogen in the reactivity series (e.g., magnesium, zinc, iron) will displace hydrogen from dilute acids; metals below hydrogen (e.g., copper, silver) do not react with dilute acids because they are less reactive.
