Hydrochloric acid - Wikipedia
Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula HCl.Hydrochloric acid has a distinctive pungent smell. It is classified as strongly acidic and can attack the skin over a wide composition range, since the hydrogen chloride completely dissociates in an aqueous solution.

Aluminium reaction to hydrochloric acid is slow to start
The reaction between aluminium and hydrochloric acid As aluminium has three electrons in its outer shell, the reaction requires a ratio of two aluminium molecules to six hydrochloric acid molecules. This is because each chlorine atom in the hydrochloric acid acquires an electron from the aluminium and loses a hydrogen atom.

Hydrochloric acid All Group 2 metals react with dilute hydrochloric acid to produce a metal chloride and hydrogen gas. The reactions get more vigorous as you go down the group. The general equation for this reaction is: X + 2HCl → XCl 2 + H 2 (where X is a 2
Acid - Wikipedia
Svante Arrhenius attributed the properties of acidity to hydrogen ions (H +) or protons in 1884. An Arrhenius acid is a substance that, when added to water, increases the concentration of H + ions in the water. Note that chemists often write H + (aq) and refer to the hydrogen ion when describing acid-base reactions but the free hydrogen nucleus, a proton, does not exist alone in water, it

Properties & Uses Explained - Hydrochloric acid
Hydrochloric acid is a molecular compound, as it is a non-mental bounding with a non-metal (hydrogen acts as a non-metal). Hydrochloric acid is also a polar covalent compound, meaning that the chlorine has a stronger pull on the electron it shares with hydrogen, then the hydrogen atom.
