C1V1 = C2V2
Where:
C1 = Concentration of the stock solution
V1 = Volume of the stock solution
C2 = Concentration of the working solution
V2 = Volume of the working solution
NOTE:
The relationship between the volumes and concentrations involved is that of
an inverse proportion; that is, when the volume of one solution is greater, the
concentration of the solution of greater volume is less.
a. Basic Rules for Solving C1V1 = C2V2 Problems.
(1)
Three of the 4 values must be known.
(2)
The units of volume and concentration must be the same respectively.
(3) It is crucial that the volume and concentration that relate to one another
are identified.
(4)
Any unit of volume or concentration may be used.
b. Example 1. How much 30.03.0
Solution. Read the problem carefully and determine the relationship that will
allow you to determine the unknown quantity.
C1V1 = C2V2
Ensure that the concentration and volume units are the same respectively.
Using the appropriate expression, substitute the given values.
C1V1 = C2V2
