Honors Chemistry - Unit 10 - Solutions Test Review

Definition of molarity

mol/L

Dilution Equation

M₁V₁=M₂V₂

Spectator Ion

Ions that do not participate in the chemical reaction; they are in solution before and after the reaction

Suspension

particles are so large that they settle out of solution unless constantly mixed

Solution

a homogeneous mixture

Solute

the substance being dissolved

Solvent

the substance doing the dissolving

electrolyte

conducts electricity

nonelectrolyte

does not conduct electricity
