The majority component of a solution is known as the __.

Solvent

The minority component of a solution is known as the __.

Solute

An solution is a solution where water is the solvent.

Aqueous

The rule 'likes dissolve likes' refers to the __ of solute and solvent interactions.

similarity

__ is a measure of the disorder or dispersion of energy of a system.

Entropy
