Dilution Of Solutions

A chemical solution is prepared by dissolving a solute in a solvent. The concentration of a solution is usually given in moles per litre (mol/L or M). This is also known as Molarity . When a solution is diluted, more solvent is added to it. The dilution equations are as follows:

     V₁M₁ = V₂M₂

     ΔV = V₂ - V₁

where
     V₁ = volume before dilution
     V₂ = volume after dilution
     ΔV = volume of solvent added during dilution
     M₁ = concentration (molarity) before dilution
     M₂ = concentration after dilution
