Question

Give equation to oxidation and reduction reaction

Answer 1

Answer:

oxidation reaction

Cu give rise to Cu+2 +2e-

oxidation reacn means loss of e-

redn reacn

F+e- give rise to F-

redn reacn means gain of e-

Answer 2

Oxidation have three definition.

1. Addition of oxygen 2.removal of hydrogen 3.removal of electrons.

Reduction also has three definition which are contrary to that of oxidation.

Example OF oxidation: Oxidation of formaldehyde give Carboxylic(formic) acid.

H-CHO + [O] --------> HCOOH

EXAMPLE OF REDUCTION:

S + H2 ---> H2S
