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'
