Question

Quizplus · Accepted Answer

The pH in the stomach during digestion is highly acidic, typically around 1.5 to 3.5, due to the presence of hydrochloric acid. The pH in the duodenum, however, is higher, around 6 to 7, because the acidic chyme from the stomach is neutralized by bicarbonate in pancreatic juice and bile. Therefore, the pH in the stomach is less than the pH in the duodenum.
