1 Using C1V1=C2V2

2 What do all those things stand for? C1= concentration 1 V1= volume 1 C2= concentration 2 V2= volume 2

3 So when do we use it? We need to make solutions from stock solutions. Example  We need to make a 1x concentration of stain but it comes as a 10x concentration. We know we need 250 ml of the 1 x solution for the experiment.

4 How do we figure it out? Fill in what we know:  C1- 1ox  V1-?  C2- 1x  V ml Now set it up 10(V1)=(1)(250ml)

5 Now do the math! 10(V1)=(1)(250ml)

6 Now do the math! 10(V1)=(1)(250ml) 10v 1 =250 ml 10

7 Now do the math! 10(V1)=(1)(250ml) 10v 1 =250 ml 10 V1= 25 mL

8 So now how do we make it… 1 st we need to figure out the difference between how much we want at the end and how much of our stock we are adding so… 250 ml- 25 ml= 225 ml (V2) (V1)

9 The Steps Obtain 25 ml of Stock Solution and bring to volume by adding 225 ml of water.
