Solubility

What is solubility?

• Ability of a substance to dissolve in a solvent

• Inability of a substance to dissolve in a solvent

• Ability of a substance to evaporate in a solvent

• Ability of a substance to solidify in a solvent

Name three factors that affect solubility.

• temperature, pressure, nature of solute and solvent

• mass, viscosity, surface area

• volume, density, pH

• color, concentration, time

How does temperature affect solubility?

• Temperature increases solubility by decreasing the kinetic energy of the solvent molecules.

• Temperature affects solubility by increasing the kinetic energy of the solvent molecules.

• Temperature decreases solubility by decreasing the kinetic energy of the solvent molecules.

• Temperature has no effect on solubility.

How does solubility affect the dissolving of sugar in tea?

• Solubility affects the amount of sugar that can dissolve in tea.

• Solubility only affects the color of the tea, not the dissolving of sugar.

• Solubility has no effect on the dissolving of sugar in tea.

• The dissolving of sugar in tea is not affected by solubility.

What is the solubility of salt in water?

• Partially soluble

• Insoluble

• Moderately soluble

• Highly soluble

How does pressure affect solubility?

• Increasing pressure generally increases the solubility of gases in liquids.

• Increasing pressure increases the solubility of solids in liquids.

• Pressure has no effect on solubility.

• Increasing pressure generally decreases the solubility of gases in liquids.

What is the difference between solute and solvent?

• The solute and solvent are both substances that are dissolved.

• The solute is the substance in which the solute is dissolved, while the solvent is the substance that is dissolved.

• The solute is the substance that is dissolved, while the solvent is the substance in which the solute is dissolved.

• The solute and solvent are the same thing.

What is solubility in everyday life?
