Saliva should be close to neutral pH, about 6.5 to 7. It’s possible that it could become acidic due to reflux/regurgitation, but I would expect it to correct it self pretty quick. The body regulates pH pretty tightly. I am not sure what else you could learn about your stomach acid levels by this test.
