Interpretation :
The option that is not a right clue that a
Concept Introduction :
A chemical reaction represents the chemical change in which new substance are produced with new appearance and properties.
Answer to Problem 1STP
Correct answer: Option D is correct.
Explanation of Solution
Reason for correct option: Option D is correct because a pure solid can be converted to pure liquid by heating which is melting process and not a chemical reaction.
Reasons for incorrect options: Option A is incorrect as formation of a solid from two clear solutions indicates chemical reaction.
Option B is incorrect as color change of red solution to blue solution indicates chemical reaction.
Option C is incorrect as addition of solid into water resulting bubbles indicates evolution of gas which indicates chemical reaction.
