Chapter 9, Problem 9.138QP

Interpretation Introduction

Interpretation:

The reason for why Hydrochloric acid is not act as an oxidizing agent should be explained.

Concept introduction:

Oxidation number:

• Oxidation number of an atom is varied by involving in reaction is called redox reaction.
• In the redox reaction, number of electron is last or gain by an atom to form an electrically neutral product is called oxidation number.
• The sum of oxidation numbers of all atoms present in molecule is zero.

Oxidizing agent:

• In the redox reaction, an atom or ion, which is gain the electrons it is called oxidizing agent.

Reducing agent:

• In the redox reaction, an atom or ion, which is last its electrons it is called reducing agent.
