The equation for the reaction between zinc and aqueous copper(II) sulfate is shown. Zn + CuSO4 → ZnSO4 + Cu
Which statement is correct?
Select the correct response:
The oxidation state of the reducing agent has changed from +2 to 0
The oxidation state of the oxidising agent has changed from 0 to +2.
The oxidation state of the reducing agent has changed from 0 to +2.
This is not a redox reaction. The solution changes from colourless to blue.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
