Oxidized - lost electrons; more positive
Reduced - gained electrons; more negative
In the following reactions, identify what is oxidized and what is reduced.
2Li(s) + F2(g) → 2LiF(s)
a. both Li and F are oxidized
b. both Li and F are reduced
c. Li is oxidized, F is reduced
d. F is oxidized, Li is reduced
Cl2(g) + 2KI(aq) → 2KCl(aq) + I 2(s)
a. Cl is oxidized, K is reduced
b. K is oxidized, Cl is reduced
c. I is oxidized, Cl is reduced
d. Cl is oxidized, I is reduced
Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s)
a. both Cu2+ and Zn are reduced
b. both Cu2+ and Zn are oxidized
c. Cu2+ is oxidized, Zn is reduced
d. Zn is oxidized, Cu2+ is reduced
