Question

Match the following with the correct answer.

A. Loss of electrons: A + B rightwards arrow C + D + e-

B. Gain of electrons: A + B + e- rightwards arrow C + D

C. The substance that is oxidized and donates electrons.

D. The substance that is reduced and accepts electrons.

E. Mg rightwards arrow Mg2+ + 2e- Poor magnesium just lost 2 electrons. Is this an oxidation or a reduction?

F. O2 + 4e- rightwards arrow 2O2- Wow, oxygen just gained 4 electrons. Is this an oxidation or a reduction?

1. Oxidation

2. Reducing agent

3. Reduction

4. Oxidizing agent

A. A + B --------- C + D + e- is called as oxidation reaction. In this reaction electrons are lost. -------------- 1

B. A + B + e- ------------ C + D is called as reduction. In this reaction electrons are gained. --------------------- 3

C. The substance that is oxidized and donates electrons acts as Reducing agent ---------------------------------- 2

D. The substance that is reduced and accepts electrons acts as Oxidising agent ----------------------------------- 4.

E. Mg --------- Mg+2 + 2e-. This is loss of electron reaction. So it undergoes oxidation and acts as reducing agent

F. O2 + 4 e- -------------- 2O-2 This is gain of electron reaction. So O2 undergoes reduction and acts oxidising agent.
