I am a student at the University of Virginia and I was looking for an answer to a question when I came upon your web page. Do you know what is the average volume and concentration of stomach HCl produced to digest an average meal? Thank you for your time.
The volume is variable among individuals. The sight, smell, taste, and presence of food stimulate the secretion of acid into the stomach. The pH of the hydrochloric acid in the stomach is about 2.0 to 3.0.
To further search for information about hydrochloric acid secretion, I would suggest you consult a nutritional biochemistry book in your library.
