Chapter 7 science

A colloid is

A mixture containing small, undissolved particles that do not settle out, particles that are too small to be seen easily but are large enough to scatter a light beam.

Concentrated solution is

A mixture that has a lot of solute dissolved in the solvent.

Sugar is an example of

A solute.when a few spoonfuls of sugar are mixed into a cup of water, sugar is the solute.

A solute is different from a solvent in a solution

Because the solute is present in a smaller amount.

A solution that contains a large amount of solute is the best described as a

Concentrated solution.

A mixture that has only a little solute dissolved in the solvent is called a

Dilute solution. Adding more solvent to a solution makes the solution more dilute.

One way to increase the solubility of water is by

Heating the water.

A suspension is a

Heterogeneous mixture.

A solution is a

Homogeneous mixture.

Decreasing the temperature

Increases the solubility of a gas in a liquid

A suspension

Is a Liquid mixture in which particles can be seen and easily separated by setting or filtration.

Solubility

Is a Measure of how much solute can dissolve in a solvent at a given temperature.

Distillation

Is a Process that can be used to separate crude oil into its components.

A solution

Is a mixture containing a solvent and at least one solute and has the same properties throughout, it is distribute evenly.

Heterogeneous mixture

Is a mixture in which you can see the different parts and can easily separate them out. And example is a trail mix.

Water

Is often called the universal solvent.

Homogeneous mixture

Is so evenly mixed that you can't differentiate the parts simply by looking at the mixture

Solutions can be

Liquids, solids, and gases.

Temperature can affect the

Solubility of a substance.the solubility of most solids increases as the temperature increases

A mixture is classified as a

Solution, colloid or suspension

Salt water is an example of a

Solution.

Concentration of a solution=

Solvent ex.water divided by solute ex salt.

Solvent

The part of solution usually present in the largest amount. It dissolves the other substances.

The solute is

The substance dissolved to form a solution.

A mixture is

Two or more substances that are together in the same place,and can be physically separated. Examples are chicken noodle soup and air.

A solution that contains less solute than it can hold at a given temperature is

Unsaturated
