Akin to its use for pickling, hydrochloric acid is used to dissolve many metals, metal oxides and metal carbonates. The conversions are often depicted in simplified equations: Zn + 2 HCl → ZnCl 2 + H 2 NiO + 2 HCl → NiCl 2 + H 2 O CaCO 3 + 2 HCl → CaCl 2 + CO 2 + H 2 O. These processes are used to produce metal chlorides for analysis or ...
Acidic drain cleaners usually contain sulfuric acid at high concentrations. [1] It can dissolve cellulose, proteins like hair, and fats via acid hydrolysis. While there are many methods for unclogging drains, one of the most effective solutions is using hydrochloric acid (HCl), a powerful chemical cleaner. [2]
Notable descaling agents include acetic acid, citric acid, glycolic acid, formic acid, lactic acid, phosphoric acid, sulfamic acid and hydrochloric acid. The calcium salts are soluble and thus washed away during dissolution or solvation. The speed of the descaling action depends on the concentration and acidity or pH of the solution provided ...
This is done by reacting it with a solution of hydrofluoric acid (HF) which fluorinates the CHCl 3 molecule and releases hydrochloric acid as a byproduct. [40] Before the Montreal Protocol was enforced, most of the chloroform produced in the United States was used in the production of chlorodifluoromethane. However, its production remains high ...
Hydrochloric acid is a common mineral acid typically used for concrete. Vinegar can also be used to clean hard surfaces and remove calcium deposits. Sulphuric acid is used in acidic drain cleaners to unblock clogged pipes by dissolving organic materials, like greases, proteins, and even carbohydrate-containing substances such as toilet tissue.
It can also be produced by the addition of hydrochloric acid to a hot, concentrated solution of mercury(I) compounds such as the nitrate: [2] Hg 2 (NO 3 ) 2 + 4 HCl → 2 HgCl 2 + 2 H 2 O + 2 NO 2 Heating a mixture of solid mercury(II) sulfate and sodium chloride also affords volatile HgCl 2 , which can be separated by sublimation .
In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid.
Similarly "spirit(s) of salt" actually meant hydrochloric acid. The concentrated, fuming, 35% acid is still sold under this name in the UK, for use as a drain-cleaning fluid. "Spirit of vinegar" is an antiquated term for glacial acetic acid "Spirit of vitriol" is an antiquated term for sulfuric acid
