Question

On the basis of physical and chemical changes, find the odd one out

statement:-

(P) Oxidation of a slice of brinjal

(Q) Burning of magnesium ribbon

(R) Crystallization of copper sulphate

(S) Corrosion of a metal​

Answer 1

(a) option is the best answer

Answer 2

The crystallization of copper sulphate is the odd one here.

• There are four different incidents mentioned in the question. We will analyse them one by one to get our answer.
• The oxidation of a slice of brinjal absolutely contains of chemical change because oxidation is a chemical reaction.
• The chemical reaction of combustion in the presence of oxygen is also included in the burning of magnesium ribbon. .
• Corrosion of metal also includes chemical reaction in the presence of moisture.
• Only, the crystallization of copper sulphate does not contain any type of chemical reaction. That's why, it's the odd one here.
