Respuesta :
The half reaction that represents the oxidation will be:
[tex]Cd(s)[/tex] → [tex]Cd^{2+}(aq)+2e^-[/tex]
- A half reaction is either the oxidation or reduction reaction component of a redox reaction.
- A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction.
Given reaction:
This is an oxidation-reduction (redox) reaction:
[tex]Cd+NiO_2+2H_2O[/tex] → [tex]Cd(OH)_2+Ni(OH)_2[/tex]
The anode is where oxidation occurs and is the positive polarity contact in an electrolytic cell.
The half reaction that represents the oxidation will be:
[tex]Cd(s)[/tex] → [tex]Cd^{2+}(aq)+2e^-[/tex]
