Ozonolysis of

ClO_{2}

produces an oxide of chlorine. The average oxidation state of chlorine in this oxide is ____.

Answer: 6

Solution

Ozonolysis of

ClO_{2}

involves reaction with ozone (

O_{3}

). The reaction is:

2 ClO_{2} + 2 O_{3} \to Cl_{2} O_{6} + 2 O_{2}

. The oxide produced is

Cl_{2} O_{6}

. To find the oxidation state of Cl: Let the oxidation state of Cl be

x

2 x + 6 (- 2) = 0

, so

2 x - 12 = 0

, giving

x = + 6

. The average oxidation state of chlorine in

Cl_{2} O_{6}

is +6.
