Gastric acid

Gastric acid is secretion produced in the stomach. It is one of the main ditotonic solutions secreted, together with several enzymes and intrinsic factors. Chemically it is an acid solution with a pH of 1 to 2 in the stomach lumen, consisting mainly of hydrochloric acid (HCl) (around 0.5%, or 5000 parts per million), and large quantities of potassium chloride (KCl) and sodium chloride (NaCl).
