Solubility and Separating Mixtures

Factors affecting the rate of Solubility

• Particle Size

• Pressure

• Concentration

• Stirring

Evaporation

• A process used to separate a solute from a solvent by heating the solution until the solvent evaporates.

• A method of cooling a liquid by adding ice to it.

• A technique for mixing two liquids to form a solution.

• A way to increase the pressure of a gas by reducing its volume.

Particle Size

• Smaller particles dissolve faster than larger particles.

• Larger particles dissolve faster than smaller particles.

• All particles dissolve at the same rate regardless of size.

• Smaller particles do not dissolve in water.

Mechanical Separation/Sorting

• A method of separating components of a mixture based on physical properties like size and shape.

• A technique used to chemically alter the components of a mixture.

• A process that involves heating a mixture to separate its components.

• A method of mixing different components to create a uniform solution.

Stirring

• Stirring a solution helps to distribute the solute particles, increasing the rate of solubility.

• Stirring a solution decreases the temperature of the solvent.

• Stirring a solution makes it more viscous and harder to mix.

• Stirring a solution has no effect on the solubility of the solute.

Magnetism

• A technique used to separate magnetic materials from non-magnetic materials.

• A method for generating electricity using magnets.

• A process for cooling materials using magnetic fields.

• A way to enhance the strength of non-magnetic materials.

Concentrated

• A solution that has a large amount of solute compared to solvent.

• A solution that has a small amount of solute compared to solvent.

• A solution that is completely solid with no liquid present.

• A solution that has equal amounts of solute and solvent.

Saturated solutions

• A solution that contains the maximum amount of solute that can be dissolved at a given temperature.

• A solution that contains no solute at all.

• A solution that can still dissolve more solute at a given temperature.

• A solution that has a higher concentration of solute than the solvent can hold.

Temperature

• Increasing temperature generally increases solubility.

• Increasing temperature decreases solubility.

• Temperature has no effect on solubility.

• Solubility is only affected by pressure.

Concentration

• The amount of a substance (solute) present in a certain volume of solution.

• The total mass of a solution divided by its volume.

• The ratio of solute to solvent in a mixture.

• The temperature at which a solution becomes saturated.
