Webb26 mars 2016 · The situation is reversed for bases. If a solution contains more hydroxide ion than hydrogen ion, it is said to be basic, and its pH is higher than 7. Remember that … WebbIn living organisms, the pH of various body fluids, cellular compartments, and organs is tightly regulated to maintain a state of acid-base balance known as acid–base homeostasis. Acidosis , defined by a pH below 7.35, is the most common disorder of acid–base homeostasis and occurs when there is an excess of acid in the body.
