An environmental chemist is investigating a sample of acid rain. To determine the concentration of sulfuric acid in the sample, the chemist performs a titration against a standard solution of potassium hydroxide, KOH\text{KOH}KOH.
The chemist uses a volumetric pipette to transfer a portion of the potassium hydroxide solution into a conical flask before adding an indicator and titrating with the acid rain sample.
Describe how the chemist should use the volumetric pipette to measure and transfer exactly 25.00 cm3 of the potassium hydroxide solution into the conical flask.
