Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
- The Arrhenius Theory of Acids and Bases. In 1884, the Swedish chemist Svante Arrhenius proposed two specific classifications of compounds; acids and bases.
- Free Hydrogen Ions do not Exist in Water. Owing to the overwhelming excess of \(H_2O\) molecules in aqueous solutions, a bare hydrogen ion has no chance of surviving in water.
- The Brønsted-Lowry Definition. In 1923, chemists Johannes Nicolaus Brønsted and Thomas Martin Lowry independently developed definitions of acids and bases based on the compounds' abilties to either donate or accept protons (H ions).
- The Brønsted-Lowry Theory of Acids and Bases. A Brønsted-Lowry acid is a proton (hydrogen ion) donor. A Brønsted-Lowry base is a proton (hydrogen ion) acceptor.
A base is a substance that forms hydroxide ions OH - when dissolved in water. For example, hydrochloric acid (HCl HCl) is an acid because it forms H+ H + when it dissolves in water. HCl(g) Water H+(aq) +Cl−(aq) H C l (g) Water H + (a q) + C l − (a q) Similarly, NaOH is a base because it forms OH - when it dissolves in water.

Jul 3, 2016 · Answer link. "HCl" (hydrochloric acid) is a strong acid. Why "HCl" is an acid can be explained on basis of many theories, like Arrhenius theory, Bronsted-Lowry acid base theory, and Lewis acid-base theory. According to Arrhenius theory, a compound which when dissolved in water dissociates and furnishes "H"^ (+) ions is an Arrhenius acid.
