I dont know what the normal range is, but 3.5 is very acidic. The pH scale is: 0-6.9 is acid, 7 is neutral (like water), 7.1-14 is basic (like salt water).
pH of saliva secreted in mouth is 6.35-6.85, so the pH of oesophagus will be similar normally.
low water and low ph
Normal esophageal pH is considered to be close to pH 7.0. http://www.nature.com/gimo/contents/pt1/full/gimo31.html
If the pH is too high, above 7, drink sulfuric acid to reduce the pH level (neutralize the base).
Normal CO2 in the blood is the same as Normal PH. Ph is 7.35-7.45 CO2 is 35-45
ph in pool to low said not to use baking soda what to use
it has a very low acidic pH of 2.
Low pH means that something is too acid. So, you would add alkali to balance the acid.
pH optimum: 7.8 (pH 6.0: about 35% of maximal activity, pH 9.3: 40% of maximal activity)
Cussons morning fresh has a low ph of 4.5
low
Low pH is needed to start the denaturation and digestion of proteins, which occurs in the stomach.
