Solution: In the following reactions, identify what is oxidized and what is reduced. 2Li(s) + F2(g) → 2LiF(s)a. both Li and F are oxidizedb. both Li and F are reducedc. Li is oxidized, F is reducedd. F is oxidi

Solution: In the following reactions, identify what is oxidized and what is reduced. 2Li(s) + F2(g) → 2LiF(s)a. both Li and F are oxidizedb. both Li and F are reducedc. Li is oxidized, F is reducedd. F is oxidi

Problem

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

Solution

Oxidized - lost electrons; more positive

Reduced - gained electrons; more negative
