Question

I know that ethanol is mixed with some ingredients as fennel which give to this its particular taste. Fennel and ethanol are mixed together. Ethanol is also mixed with water. The analogy is 60 percent water 40 percent ethanol.

When we add some water more the fennel gets free from ethanol and the drink takes its white color.

The question is why adding some water more changes the equilibrium between fennel and ethanol?

Answer 1

When water is added to a mixture of fennel and ethanol, it disrupts the hydrogen bonding between ethanol molecules and causes ethanol to dissolve in water. This changes the equilibrium between fennel and ethanol and results in a white-colored drink.

Step-by-step explanation:

When water is added to a mixture of fennel and ethanol, it changes the equilibrium between fennel and ethanol because water can disrupt the hydrogen bonding between ethanol molecules. Ethanol molecules form hydrogen bonds with each other, as well as with water molecules.

When water is added, it competes with ethanol for hydrogen bonding, causing ethanol molecules to separate from fennel and dissolve in water. As a result, the fennel is no longer bound to ethanol and the drink becomes white in color.
