Question
Chapter 4.8, Problem 4.11Q
Interpretation Introduction
Interpretation:
The oxidizing agent, reducing agent, substance oxidized, and substance reduced during formation of calcium sulphide has to be identified.
Concept Introduction:
Oxidation is defined as a loss of electrons, loss of hydrogen atoms, or gain of oxygen
atoms.
Reduction is defined as a gain of electrons, gain of hydrogen atoms, or loss of oxygen atoms.
Reducing agent: Substances that undergoes oxidation itself and reduces other substance is called reducing agent.
Oxidizing agent: Substances that undergoes reduction itself and oxidizes other substance is called oxidizing agent.
The characteristics of oxidizing and reducing agents are given below as,
| Oxidizing agent | Reducing agent |
| Is reduced | Is oxidized |
| Gains electrons | Loses electrons |
| Causes oxidation | Causes reduction |
