Answer to Question #270808 in Physical Chemistry for Dolphy

Question

Balance the following equations using the change in oxidation number method.

2.Cl2+ I2+ H2O⎯→HIO3 + HCl

Balanced equation: _______________________________________________________

Oxidizing agent:

(1 pt) ____________________

Reducing agent:

(1 pt ) ____________________

Answer 1

I₂ (s) + 5 Cl₂ (g) + 6 H₂O (l) → 2 HIO₃ (aq) + 10 HCl (aq)

This is an oxidation-reduction (redox) reaction:

2 I⁰ - 10 e^- → 2 I^V

(oxidation)

10 Cl⁰ + 10 e^- → 10 Cl^-I

(reduction)

I₂ is a reducing agent, Cl₂ is an oxidizing agent.
