Answer 2

Water is the solvent in a cup of milk.

Explanation:

• Milk can be considered as a solution because it is basically a mixture containing proteins, lactose, trace elements, lipids, fats and other substances in water without any bonding. Here proteins, lactose, trace elements, lipids, fats and other substances are solute whereas water is the solvent.

• However, milk is generally kept in the category of emulsion.

• Milk has more than one phase suspended in it.

• Unlike a solution, where we observe the solute and solvent having only one phase, the milk here is an emulsified colloid.

• It has a dispersed phase (or the suspended particles) and a continuous phase (the medium of suspension), which is a result of phase separation.

• So, milk is categorized under colloidal emulsion.
