5.2 Solution Concentration

solution

a homogeneous mixture of 2 substances

solvent

the majority component of a solution

solute

the minority component of a solution

aqueous solution

solution in which water acts as the solvent

dilute solution

a solution that contains a very small amount of solute relative to the amount of solvent

concentrated solution

a solution that contains a large amount of solute relative to the amount of solvent

molarity (M)

common way to express solute concentration, amount of solute divided by the volume of solution (in liters)

M=n/V

molarity equation

solution

Molarity = amount of solute/volume of ___________ (solvent/solution)

molar (M)

unit of molarity, also called mol, not to be confused with moles

stock solutions

a highly concentrated form of a solution used in laboratories to make less concentrated solutions via dilution

M₁V₁ = M₂V₂

dilution equation
