Document Summary
Ph scale humans live in a tiny ph scale. If you have 1 mol/l of h+, your ph is going to zero = battery acid. As you decrease your h+ concentration, your ph will increase. Most acidic chemical in our body is the gastric juice. The least acidic in our body is the saliva. On the alkaline side, ph is greater than 7: urine is the only thing that changes its ph dramatically, then blood - most important thing we need to measure. Normal ph range is 7. 35 7. 45. Below this range; it is physiological acidosis. Above this range; it is physiological alkalosis. Urine can be as high as ph of 8 and stomach acid of a ph of 1. 5. The most important fluid to consider is human venous blood and it is normally between 7. 35 to 7. 45. Babies are very tolerant of very low ph.
