Some batteries have lithium and cobalt in them. The Li0 gets oxidized to Li1+, and Co2+ gets reduced to Co0.
Write a balanced reaction for Li oxidation and Co reduction. Make sure the stoichiometry and charge are balanced!
Homework Answers
Reduction of Co2+(aq)
Co2+(aq) + 2e = Co(s)
Oxidation of lithium
Li(s) = Li+(aq) + e ( multiply by 2 )
2 Li(s) = 2 Li(s) + 2e
Add them , we get
2 Li(s) + Co2+(aq) = Co(s) + 2 Li+(aq)
If you have any questions please comment
If you satisfied with the solution please rate it thanks

In some chemical reactions, one species loses electrons by transferring them to another species. Consequently, the products have different charges than the reacting elements or ions. Losing electrons is called oxidation and gaining electrons is called reduction. Because free electrons cannot remain in a system, both reduction and oxidation must occur together. Such reactions are termed redox reactions. Just as atoms must be balanced in a chemical reaction, the charges in a redox reaction must also be balanced. Reduction and...
