Describe a method that could be used to determine which metal is more reactive.

Question

You are given two metals zinc and copper. Describe a method that could be used to determine which metal is more reactive. In your explanation, outline the worded chemical equations for the reactions that will occur in your experiment.

A detailed explanation of a valid prediction and thorough steps of how you will test your prediction for outlining the results of the chemical reaction

Answer 1

One simple way to do this is add the metal to hydrochloride acid. The Zn will react immediately to form bubbles of hydrogen gas; the Cu doesn't react. Since the Zn reacts immediately, it's the more reactive metal.

Zn_(s) + 2 HCl_(aq) → H_2(g) + ZnCl_2(aq)
