Chapter 19, Problem 35E

Interpretation Introduction

Interpretation:

The redox equation for the redox reactants ${\text{Br}}_{\text{2}}$ and ${\text{I}}^{-}$ is to be stated. The direction of the reaction that would be favored at equilibrium is to be predicted.

Concept introduction:

The process in which oxygen is added or a hydrogen atom is removed from a substance is known as oxidation and the process in which hydrogen is added or an oxygen atom is removed from a substance is known as reduction. The addition of an electronegative atom to another substance is also known as oxidation and the addition of an electropositive atom to another substance is known as reduction. A reducing agent is a substance that undergoes oxidation and an oxidizing agent is a substance that undergoes reduction.
