Question

su The table gren below shows the reactions of metals with the solutions of metal salts.
(5 marks)
Reaction of Metal x with: Reaction of Metal Y with: Reaction of Metal Z with
suprate - No reaction X sulphate → No reaction X sulphate → No reaction
Y spate Displaces Y Y sulphate → No reaction Y sulphate → Displaces Y
Zsulphate Displaces Z Z sulphate → No reaction Z sulphate → No reaction
al On the basis of your observation of the data given above, arrange the metals X, Y,
and Z in order of increasing reactivity and justify your answer.
Will cooper react with a salt solution of zinc chloride? Justify your answer.​
