Solutions

The concentration of a solution refers to the

• molecular weight of the solvent

• temperature of the solution

• amount of solute in the solution

• physical state of the solution

A solution with a low concentration is said to be

• supersaturated

• soluble

• saturated

• dilute

If a large amount of a substance can dissolve in a solvent, it has

• a low solubility

• a high solubility

• unlimited solubility

• no solubility

A substance such as oil does not dissolve in water because

• both substances contain polar molecules

• both substances contain nonpolar molecules

• water molecules are polar and oil molecules are nonpolar

• water molecules are nonpolar and oil molecules are polar

A solution is a mixture with ingredients that

• always react chemically to form a new substance

• cannot be physically separated from each other

• are spread evenly throughout

• clump together in solution

The most common solvent is

• water

• oil

• oxygen

• salt

What is true of solutions?

• They can be liquid only.

• They can be liquid or gas only.

• They can be liquid or solid only.

• They can be liquid, solid, or gas.

The freezing point of a solution is always

• lower than the freezing point of the solvent

• higher than the freezing point of the solvent

• the same as the boiling point of the solvent

• higher than the boiling point of the solvent

The mixture of gold and copper used in jewelry is
