Edexcel IGCSE Chemistry 2.16 Metal Displacement Reactions Questions question 1

[Maximum number: 1]

A student investigates the reaction between zinc and copper(II) sulfate solution.
This is the equation for the reaction.

Zn( s)+CuSO4(aq)→ZnSO4(aq)+Cu( s)\mathrm{Zn}(\mathrm{~s})+\mathrm{CuSO}_{4}(\mathrm{aq}) \rightarrow \mathrm{ZnSO}_{4}(\mathrm{aq})+\mathrm{Cu}(\mathrm{~s})

This is the student's method.
Step 1 add 25.0 cm325.0 \mathrm{~cm}^{3} of copper(II) sulfate solution to a glass beaker
Step 2 record the temperature of the solution
Step 3 add between 5 g and 6 g of zinc powder (an excess) and stir the mixture
Step 4 record the highest temperature reached

State the colour change in the solution.
