1. Give reasons for the following: when '30 ml' of ethanol and '30 ml' of water are mixed, the volume of resulting 'solution. is more than '60 ml'. Ans: In ethanol and water, the molecules are by. drogen bonded. When these are mixed 't 0' form a solution, each liquid tends to break the hydrogen bonds of the other liquid. The attractive forces decrease. The total volume of the solution becomes more than '60 m'

Explanation

In ethanol and water, the molecules are by. drogen bonded. When these are mixed .t 0. form a solution, each liquid tends to break the hydrogen bonds of the other liquid. The attractive forces decrease. The total volume of the solution becomes more than .60 m.
