Question:
Give below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: The surface tension of a liquid is the combined strength of the polar of dispersion forces that are pulling on the molecules in the surface of the liquid.
Reason R: The addition of small quantities ion of impurities will alter the surface tension.
In the light of the above statements, choose the most appropriate answer from the options given below:
