WebAn arterial blood gas (ABG) test is a blood test that requires a sample from an artery in your body to measure the levels of oxygen and carbon dioxide in your blood. The test also checks the balance of acids and bases, known as the pH balance, in your blood. Your body normally tightly regulates the amount of oxygen and carbon dioxide in your ... WebIntroduction The purpose of this experiment is to perform a potentiometric titration of an acid using a glass electrode and a pH meter. The potential that develops across the glass membrane of the electrode is proportional to the concentration (more exactly, the activity) of …
