What is the pH of the hydrochloric acid (HCl) secreted by the stomach?

Answer 1-2

A pH of 1-2 is a nasty acid, capable of denaturing (altering the shape) many proteins making digestion easier and killing bacteria. This low pH also facilitates the absorption of vitamin B12 and minerals such as calcium.
