- A stir plate

Procedure:

1. Put on your safety goggles and gloves.

4. In a fume hood, carefully add 1.08 mL of concentrated H2SO4 to 1 L of deionized water in a beaker.

5. Stir the solution with a magnetic stir bar until the H2SO4 is completely dissolved.

6. Transfer the solution to a graduated cylinder and add deionized water up to the 1 L mark.

7. Stir the solution again to ensure that it is well-mixed.

Your 0.02 M H2SO4 solution is now ready to use. Remember to always handle concentrated H2SO4 with care, as it is a corrosive substance.
