Question

. When Metal P being more reactive reacts with copper sulphate produces Q and R. (4)

i. Identify P, Q, R. ii. Name the colour of copper sulphate

iii. Write the balanced chemical equation of the above reaction.

iv.What type of reaction it specifies?​

Answer 1

Answer:

on adding zinc to CuSO

4

solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution because zinc is more reactive metal which displaces less reactive metal from its solution.

This is indicated by a colour change from blue to colourless.

CuSO

4

solution has a blue colour while ZnSO

4

solution is colourless.

Zn+CuSO

4

→ZnSO
