- 1). Measure out 1 liter of water and pour this amount of water into a 2-liter beaker. You can use a large graduated cylinder to measure the water or simply fill the beaker directly and use the graduation marks on the side of the beaker to tell when you have added enough water. The use of a 2-liter beaker allows you to make 1 liter of nitric acid solution without worrying about overflowing the container. Ensure that you label the beaker first to indicate that it will be holding dilute nitric acid.
- 2). Measure out 0.063 milliliters of 15.8 molar nitric acid, using an Eppendorf pipette to draw up the appropriate volume. This type of pipette is designed to allow accurate withdrawal and dispensing of very small volumes of liquid.
- 3). Dispense the 0.063 milliliters of nitric acid into the liter of water. Stir the solution well for several minutes to mix. You now have a solution of nitric acid with a pH of 3.
