Module 13: Properties of Solutions

Boiling Point

the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure

Insoluble

material with a low solubility

Molarity

the concentration of a substance in moles per liter of solution

Parts per million(ppm)

the ratio between the parts of solute per million parts of solution

Percent by volume

the concentration of a solution expressed as the ratio between the volume of the solute and total volume of the solution, expressed as a percent

Percent mass

the concentration of a solution expressed as the ratio between the mass of the solute and the total mass of the solution, expressed as a percent

Saturated

a solution containing the maximum amount of solute that will dissolve at a given temperature

Solubility

a measure of how much solute will dissolve in a certain amount of solvent at a specific temperature

Soluble

material with a high solubility

Solute

the substance being dissolved

Solution

a homogeneous mixture of substances in the same physical state

Solvent

the substance that dissolves the solute

Supersaturated

a solution that contains more solute than would dissolve in a saturated solution at a given temperature

Unsaturated

a solution in which more solute can be dissolved at a given temperature

Vapor

the gaseous state of a substance that is normally a liquid at room temperature

Vapor Pressure

the pressure a vapor exerts
