Check what you remember
Read the wording for your board, then hide it and explain Reactivity series and the position of hydrogen in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The metal must be more reactive than hydrogen for the reaction to occur, so metals such as copper, silver and gold do not react with dilute acids.
