Chapter ER, Problem 6PQ

Interpretation Introduction

Interpretation:

The reaction which requires oxidizing agent to produce the indicated product has to be given.

Concept Introduction:

Redox reactions:

Redox reactions are comprised of two parts a reduced half and an oxidized half which occur simultaneously.  The reduced half gains electrons and the oxidation number decreases, while the oxidized half loses electrons and the oxidation number increases.  There is no net change in the number of electrons in a redox reaction.  Those given off in the oxidation half reaction are taken up by another species in the reduction half reaction.

Reducing and oxidizing agents:

The two species that exchange electrons in a redox reaction are given special names.

• The ion or molecule that accepts electrons is called the oxidizing agent by accepting electrons it causes the oxidation of another species.
• The species that donates electrons is called the reducing agent when the reaction occurs, it reduces the other species.
