Question

Write half reactions for the following reaction

Zn(s)+ Cu2+(aq) +SO4 2- (aq) --> Zn2+(aq)+ SO4 2-(aq)+ Cu(s)

Answer 1

Zn (s) --------> Zn2+ (aq) + 2 e– oxidation
Cu2+ (aq) + 2 e– ------> Cu (s) reduction

SO42− ions are spectator ions you can cancel them on both side of the equation

Answer 2

Thank you so much!
