When you are making up a 0.1 nitric acid solution from 1M and you only want say 10mls, what would you do to save the waste?

To make 10 mL of 0.10 M HNO3 from 1 M HNO3, use the general dilution equation.
C1V1 = C2V2
1 M x V1 = 0.10 M x 10 mL
V1 = 1 mL
Pipette 1 mL of 1 M HNO3 into a small 10-mL volumetric flask. Then add water to fill the volumetric flask to the 10-mL mark (~ 9 mL H2O).
You could also use a 10-mL graduated cylinder, but the markings on the cylinder are not as accurate as they are on a volumetric flask.
