Diluting Solutions to Prepare Workable Solutions

Concentration is the amount of a substance that exists in a given volume of a solution. And we humans can lessen the concentration of a substance by diluting it. OMG wow so cool.

Wait, what is diluting you ask? This is the process of making a liquid thinner or weaker by adding water or another solvent into it.
Here is a picture of dilution                                            

As more solvent is added to each test tube, the solvent starts to get weaker or thinner.








You might say "We learned this already come on man/woman."

BUT WAIT IM NOT DONE YET MY PUPILS. This leads to the important part of this chapter.

The equation:  moles solute before = moles solute after.

WHATTTT???

In terms of molarity and volume: M1L1 = M2L2

*Note* Subscrite 1 means before and the subscript 2 means after

Here is an example :  Ex.  What volume of 8.00 M of HCl is used to make up 2.00L of 0.500 HCl

REMEMBER TO USE THE EQUATION

L1 = M2 x L2                     L1 = 0.500M x 2.00L
        -----------                  -----------------        =          0.125 L
             M2                               8.00 M
