CHEMISTRY-Reduction and Oxidation (REDOX)

Question 1

What is Oxidation?

Answer 1

Gain of Oxygen, Loss of Hydrogen or Loss of Electrons

Question 2

What is Reduction?

Answer 2

Loss of Oxygen, Gain of Hydrogen or Gain of Electrons

Question 3

What is Redox?

Answer 3

Oxidation and Reduction occurring at the same time this is best expressed in Ionic equations

Question 4

In this equation witch is being Reduced and which is being Oxidised
2Fe (s)+3C(s)→4Fe(s)+3CO (g)

Answer 4

Cu → CuO is being Oxidised

H2O → H2 is being Reduced

Question 5

What is Reducing Agent?

Answer 5

A reducing agent, or reductant, loses electrons and is oxidized in a chemical reaction. A reducing agent is typically in one of its lower possible oxidation states, and is known as the electron donor. A reducing agent is oxidized, because it loses electrons in the redox reaction

Question 6

What is Oxidising Agent?

Answer 6

An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced

Question 7

Examples of reducing agents

Answer 7

Examples of reducing agents include the earth metals, formic acid, and sulphate compounds.

Question 8

Examples of reducing agents

Answer 8

.Examples of oxidising agents include halogens, potassium nitrate, and nitric acid.
