Chapter 16, Problem 8E
Interpretation Introduction

Interpretation:

To complete the blank given in the statement “For a neutral molecule, the oxidation states of the individual atoms must add up to _____.”

Concept introduction:

Oxidation states or the oxidation number is a + or – value that is given to the element in order to represent the number of electrons lost or gained when undergoing a chemical combination. In case of loss of electrons, the oxidation number is positive. In case of gain of electrons, the oxidation number is negative.

Instructions: Balance the following reactions based on the Oxidation State Method and Half Reaction Method. Balancing Redox Reactions:
Oxidation Number Method  KCIO3(aq) + HBr(aq) ---- Br2(I) + H2O (I) + KCI (aq)
(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. An acidic and a basic solution may be used to balance the redox reaction when the oxidation number method is employed.  The final step in balancing redox reactions using the oxidation number method is to balance by inspection. 2. In the oxidation number method of balancing redox reactions, there is a need to add water and hydroxide ions on both sides of the chemical reaction. The oxidation state of oxygen is always (-2) except for peroxides.  3. In the half-reaction method of balancing redox reactions, the reaction is divided into three half-reactions. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is an oxidizing agent. 4. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent.  In a redox reaction, the oxidation…
