Question

1. The equation for the reaction between zinc and aqueous copper(II) sulfate is shown.

Zn + Cuso, → ZnSO, + Cu

Which statement is correct?

a. The oxidation state of the oxidising agent has changed from 0 to +2.

b. The oxidation state of the reducing agent has changed from 0 to +2.

c. The oxidation state of the reducing agent has changed from +2 to 0

d. This is not a redox reaction. The solution changes from colourless to blue.

Answer 1

The oxidation state of the reducing agent has changed from 0 to +2.

Step-by-step explanation:

reducing agent is anything that loses electron or gains oxygen

in this case, zinc
