Question

In which situation can a mixture always be called a solution?

when one of its components is a gas

when there is no solvent in the mixture

when its components are made up of different types of particles

when the mixture is homogeneous

Answer 1

The last one is correct. Homogeneous mixtures are considered solutions, because it is uniform in composition throughout.

Answer 2

Answer:

when the mixture is homogeneous

Explanation:

A homogeneous mixture has a uniform composition whereas a heterogeneous mixture does not. A homogeneous mixture exists in a single phase whereas a heterogeneous mixture has more than one phase. For example, salt and water or salt solution is a homogeneous mixture but gravel and water is a heterogeneous mixture. Thus a homogeneous mixture is called a true solution.
