Question

Assertion:- When 2 ml of dettol is dissolved in water then we get the smell of dettol from the water. We put this solution containing dettol in another beaker containing clear water and they are mixed in the ratio of 9:1 (9 parts of clear water to 1 part of dettol solution) at every step of dilution then it takes infinite similar steps to get a water free from smell of dettol

Reason:- Particles of matter are too tiny in size.

Solution

The correct option is B

Assertion:- True

Reason:- True


When 2ml of dettol is dissolved in water then we get the smell of dettol from the water. As we put this solution containing dettol in another beaker containing clear water and they are mixed in the ratio of 9:1 (9 parts of clear water to1 part of dettol solution) then at every step of dilution we are able to sense the smell of dettol from the solution. It takes infinite number of steps to obtain a solution without smell of dettol. So it proves that there are millions of tiny particles in just 2ml of dettol which keeps on dividing themselves into smaller and smaller particles.
