When a single salt crystal is added to a cool liquid, large crystals form. Which statement about the original cool liquid is correct? A) The liquid is a heterogeneous mixture because the crystals can be easily separated from the liquid

B) The liquid is a pure substance because it was made up of a single compound

C) The liquid is a pure substance because it was uniform before the crystal was added

D) The liquid is a homogenous mixture because the substance that formed the large crystals was uniformly dissolved

The liquid is a homogeneous mixture because the substance that formed the large crystals was uniformly dissolved.

A solution is composed of a solute and a solvent. A solution is a typical example of a homogeneous mixture.

We define a solution as any combination of solute and solvent. A solution can be regarded as a homogeneous mixture since the solute is uniformly distributed throughout the solution. The solute and solvent constitutes one phase.

When a salt crystal is added to the solution, crystallization is induced and large crystals of solute form.
