Chemistry help gcse
A student is given 3 metals x y and z
The metals are magnesium iron and copper
Plan an investigation to identify the three metals by comparing their reactions with dilute hydrochloride acid
Your plan should give valid results


Thank you xx

To identify the elements by different observations.

No I don’t sorry all i know is that there needs to be a method involving HCl but there’s no required practice I can recall unless it’s about reactivity

I would say something like react equal amounts of each metal with excess HCl and record results/observations. Then state what each of the metals should do (as Äries said) and maybe why (reactivity series), and compare them to the results from the experiment. Maybe include the generic wear safety goggles and repeat experiment too if you don't think you've hit enough marking points. (Obviously your answer would be more detailed though)
