Model 3 The Model: Dilution Process of dilution: add solvent to conc. soln. x X хх "concentrated" pure solvent "dilute" solution of solute X solution of solute X (X's are in motion.) (X's are in motion.) dilution formula: Mainal Vinitial "Minal Vánel (or Mi V - M; V) 1) When a solution is diluted, additional solvent is added to the more concentrated solution. How does the amount of solute in the initial (concentrated) solution compare to the amount of solute in the final (dilute) solution? 2) By referring to the model, justify the dilution formula. Explain why the product of the solution's initial concentration (molarity) and initial volume is equal to the product of the solution's final concentration and final volume.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
