Question

For each of the following equations

a) what species is oxidized

b) what species is reduced

c) what is the oxidizing agent

d) what is the reducing agent

EQUATION 1

ClO- + 2 H+ + 2e- --> Cl- + H2O

2 I- --> I2 + 2 e

_________________________________

ClO- + 2 H+ + 2 I- --> Cl- + I2 + H2O

EQUATION 2

2 S2O3 2- --> S4O6 2- + 2 e

I2 + 2 e- --> 2 I-

_________________________________

2 S2O3 2- + I2 --> S4O6 2- + 2 I

EQUATION 3

ClO- + 2 H+ + 2 I- --> Cl- + I2 + H2O

2 S2O3 2- + I2 --> S4O6 2- + 2 I

______________________________________

ClO- + 2 H+ + 2 S2O3 2- --> Cl- + H2O + S4O6 2-

EQUATION 1

ClO- + 2 H+ + 2e- --> Cl- + H2O; ClO- is being reduced ... H+ is the reducing agent

2 I- --> I2 + 2 e ; I-2 is being oxidized ... ClO- is the oxidiziung agent

EQUATION 2

2 S2O3 2- --> S4O6 2- + 2 e; S2O3 2- this is being oxidized; it is the reducing agent

I2 + 2 e- --> 2 I-; I2 is being reducied, it is the oxidizing agent

EQUATION 3

ClO- + 2 H+ + 2 I- --> Cl- + I2 + H2O ; ClO- is being reduced, ; it acts as oxidizing agents

2 S2O3 2- + I2 --> S4O6 2- + 2 I; S2O3-2 is being oxidized, it acts a the reducing agent
