Acid Stomach

when you mix hydrochloric acid with water to create the simulated gastric acid, which is the correct pH?

when you mix hydrochloric acid with water to create simulated gastric acid, the pH did you need the solution, to be precise? I have read that stomach acid has a pH of 2-4, but I also read that stomach acid is hydrochloric acid pH 1, which means it is at a concentration of 0.1 mol / liter. So what should I dilute my final solution pH?

Secretions the wall of the stomach have a pH between 0.8 and 1. This is a very corrosive acid that normally destroy cells tissue. Although the stomach lining is protected by a layer of mucus that prevents contact with the cells themselves, it would be a bit risky to have this level of acidity in the ever-persistent stomach. In practice, during digestion, the stomach does not contain liquids ingested by mouth. It will also be other substances such as proteins that buffer the acidity level. These factors will reduce the acidity actually averaged around 2 -4 pH depending on the amount of additional water and stomach contents were swallowed. I would use pH 2 -4, for example 3, as the average normal pH or maybe 2 if you want to simulate conditions at the beginning of the digestive process. Take care using concentrated HCl!
