Detailed explanation-1: -Gastric juice is made up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins.

Detailed explanation-2: -Stomach Acid In chemical terms, 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).

Detailed explanation-3: -Stomach acid’s low pH level is largely due to hydrochloric acid (HCl). However, there’s only a very small amount of HCl in stomach acid. Other components include potassium chloride (KCl) and sodium chloride (NaCl). The cells lining your stomach wall secrete this acidic trio.
