Dilute a solution

Your goal: Explain why dilution changes concentration while preserving solute amount.

A focused reading from Molarity, Solution Preparation and Dilution. Reading time is a Chem Help estimate.

Optional prerequisite review

Describe solution concentration

Review if useful. These suggestions never lock a step.

Dilution

Adding solvent spreads the same moles of solute through a larger volume. Because moles do not change, M₁V₁ = M₂V₂. The volumes may be in any unit as long as both sides match, which makes millilitres perfectly acceptable here.

M₁V₁ = M₂V₂
