Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism . [ 1 ]
Acetic acid injection into a tumor has been used to treat cancer since the 1800s. [53] [54] Acetic acid is used as part of cervical cancer screening in many areas in the developing world. [55] The acid is applied to the cervix and if an area of white appears after about a minute the test is positive. [55]
Acetic acid is an example of a weak acid. The pH of the neutralized solution resulting from HA + OH − → H 2 O + A −. is not close to 7, as with a strong acid, but depends on the acid dissociation constant, K a, of the acid. The pH at the end-point or equivalence point in a titration may be calculated as follows.
Simply because a substance does not readily dissolve does not make it a weak electrolyte. Acetic acid (CH 3 COOH) and ammonium (NH + 4) are good examples. Acetic acid is extremely soluble in water, but most of the compound dissolves into molecules, rendering it a weak electrolyte. Weak bases and weak acids are generally weak electrolytes.

In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction
Common nonvolatile acids in humans are lactic acid, phosphoric acid, sulfuric acid, acetoacetic acid, and beta-hydroxybutyric acid. Humans produce about 1–1.5 mmoles of H + per kilogram per day. [1] Most nonvolatile acids are excreted by the kidneys. Lactic acid is usually completely metabolized by the body, and is thus not excreted from the ...
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids , whose acidity is associated with their carboxyl group –COOH. Sulfonic acids , containing the group –SO 2 OH, are relatively stronger acids.
