Facts About Hydrochloric Acid
Hydrochloric acid is a solution of hydrogen and chlorine, otherwise called, hydrogen chloride (HCl) that can be found in water. This substance is a highly acidic, strong, mineral acid which is naturally exist within gastric acid which is one of the primary elements that works in the stomach to digest food and get rid of waste matter. Gastric acid also works in the body as a shield against bacteria in order to ward off infection. The gastric acid comprises mainly of hydrochloric acid which break down the stomach contents.
Chloride (Cl minus) and hydrogen (H plus) ions are excreted separately in the stomach region which rest at the top of the stomach by parietal cells of the gastric mucosa into a secretory system known as canaliculi before it enters the stomach lumen. After leaving the stomach, the hydrochloric acid of the chyme is neutralize in the duodenum by sodium bicarbonate. The intestinal tract is guarded from the strong acid by the release of a thick, protective mucus layer, and by secretin induced buffering with sodium bicarbonate. If hydrochloride is present in the esophagus, it can aggravate the lining of the esophagus and lead to the sensation like peptic ulcers or heartburn.
Apart from being naturally produced in the body, hydrochloric acid is commonly used as a powerful inorganic acid in many industrial processes. Throughout the Middle Ages, it was utilized by alchemist in the pursuit of the philosopher’s stone, and later on by European scientists such as Davy, Glauber and Priestley in their scientific studies. Historically it was named ‘muriatic acid’ or ‘spirits of salt’, developed from vitriol and regular salt. Hydrochloric acid became widely used at the start of the Industrial Revolution, when it was employed in the chemical industry as a chemical reagent in the extensive manufacturing of vinyl chloride used to make PVC plastic, and MDI/TDI for polyurethane.
Hydrochloric acid is mainly used to produce chlorides, for distilling ore in the manufacturing of tin and tantalum, for the pickling and cleansing of metal products, in electroplating, in eliminating scale from boilers, to neutralize basic systems, as a laboratory reagent, as a catalyst and substance in organic syntheses, in the fabrication of stimulants and dyes, for hydrolyzing starch and proteins in the preparation of certain food products and in the photographic, textile, and rubber business. It is also used in numerous smaller-scale purposes, involving household cleaning, production of gelatin and other food preservatives, descaling, and leather processing. About 20 million metric tons of hydrochloric acid is produced yearly.
Potassium nitrate which is a chemical compound is also used to safely store food as a common ingredient of salted meat since the Middle Ages, though its use has been mostly discontinued and replaced by sodium nitrate (and nitrite) because they are more reliable in safeguarding food from bacterial infection. But it is still used in some food products, such as charcuterie and the brine used to make corned beef. Potassium nitrate was also used long ago for a number of burning fuses, for example slow matches, stimulant in amateur rocket propellants, and in several fireworks such as smoke bombs. The major commercial source of the nitrate ion during the Late Middle Ages through to the 19th century is decaying urine.
As compost, potassium nitrate is used as a contributor of nitrogen and potassium, which is two of the macro nutrients for plants. Potassium nitrate is also the main component for tree stump remover because it accelerates the natural decaying of the stump. It is used as a solution in the heat treatment of metals in the post-wash. It works well as a quick-fix rust inhibitor because of its capability to oxidize, water contents at a low cost. It has also been used in the production of ice cream and can be identified in some toothpaste particularly created for delicate teeth. Potassium nitrate is also one of the three elements of black powder, along with pulverized charcoal and sulfur, where it works as an oxidizer.
