What Reactivity series and reduction means in Chemistry GCSE, as defined for AQA.
Definition of Reactivity series and reduction
Check what you remember
Read the wording for your board, then hide it and explain Reactivity series and reduction in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
If the metal is more reactive than hydrogen, its ions are less easily reduced, so H⁺ ions are reduced instead and hydrogen gas is produced.
