Hydrochloric acid
Hydrochloric acid is a strong corrosive acid that is commonly used as a laboratory reagent. It is formed by dissolving hydrogen chloride in water. Gastric acid is the hydrochloric acid component of gastric juice.
Molecular formula HCL[1], the acid is monoprotic- one proton is able dissociate from the molecule to lower pH. It is a strong Brønsted–Lowry acid as it has a high Ka[2] and donates a proton.[3]
HCL is routinely used in chemical research laboratories and manufacturing plants. Its applications include the large-scale production of certain compounds (such as vinyl chloride for polyvinyl chloride (PVC) plastic), removal of rust and scale from metals, petroleum production, and ore processing.
How HCL dissociates in water:
HCl + H2O ⇌ H3O+ + Cl− [4]
