Outline a plan the student could use to investigate the relative reactivity of the four
metals, W, X, Y and Z.
The plan should use the fact that all four metals react exothermically with dilute
sulfuric acid
You should name the apparatus used and comment on the safe use of the
chemicals. You can number your points or bullet point below.
