Dilution and concentration of solutions
• After dilution or concentration of a solution, the change in the
volume or the quantity is inversely proportional to the ratio or
percentage strength.
Concentration X Volume = Concentration X Volume
(before dilution)
(after dilution)

C1V1 = C2V2

• C= Concentration (% strength) , V= Volume

C1Q1 = C2Q2

• C= Concentration (% strength), Q= Quantity
