Question

What is the ph of stomach and oral cavity

Answer 1

The pH of stomach is from 1-2 to 4-5

Answer 2

pH of stomach is 1.5 to 3.5

The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, the acidity being maintained by the proton pump H+/K+ATPase. The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline 

pH of oral cavity

The mean pH (+/-s.d.) of all sites was 6.78 +/- 0.04 with significant differences between mean pH values in the palate (7.34+/- 0.38), the floor of the mouth (6.5 +/- 0.3), the buccal mucosa (6.28 +/- 0.36) and the tongue (6.8+/- 0.26).
