What is the typical pH level of the stomach?

The typical pH level of the stomach is between 1 and 2, which is considered highly acidic. This acidic environment is primarily due to the presence of gastric acid, mainly hydrochloric acid (HCl), produced by the stomach lining. The low pH plays a crucial role in digestion, as it aids in breaking down food, activates digestive enzymes like pepsin, and helps to kill harmful microorganisms that may be ingested with food.

Maintaining this acidic environment is essential for proper digestion and overall gastrointestinal health. It also facilitates the absorption of certain nutrients and minerals. The other options suggest a higher pH, which does not reflect the true acidic nature of stomach contents.
