Question

6. The process of reduction involves (a) addition of oxygen (b) addition of hydrogen (c) removal of oxygen (d) removal of hydrogen
​

Answer 1

Explanation:

Reduction is a process which involves; removal of oxygen, addition of hydrogen, removal of non-metal, addition of metal, decrease in +ve valency, gain of electrons and decrease in oxidation number.

Answer 2

Reduction Chemical Reaction:

• Reduction is a sub-type of REDOX reaction in which the following changes occur:

1. The substance undergoing reduction experiences reduction in the oxidation number.

2. Reduction reactions also mean addition of hydrogen (or any electro-positive atom) to the molecule.

3. Reduction can also refer to removal of oxygen (or any other electro-negative atom) from the molecule.

• Please note that : isolated reduction reaction are not possible. Reduction reactions occur simultaneously with oxidation reactions and hence we name them as REDOX REACTIONS.
