Most hydrogen chloride is consumed in the production of hydrochloric acid. It is also used in the production of vinyl chloride and many alkyl chlorides. [13] Trichlorosilane, a precursor to ultrapure silicon, is produced by the reaction of hydrogen chloride and silicon at around 300 °C. [18] Si + 3 HCl → HSiCl 3 + H 2
Hydrochloric acid has been used for dissolving calcium carbonate, e.g. such things as de-scaling kettles and for cleaning mortar off brickwork. When used on brickwork the reaction with the mortar only continues until the acid has all been converted, producing calcium chloride, carbon dioxide, and water: CaCO 3 + 2 HCl → CaCl 2 + CO 2 + H 2 O
More dramatically, a long-chain hydrocarbon like squalene (C 30 H 62) has a viscosity an order of magnitude larger than the shorter n-alkanes (roughly 31 mPa·s at 25 °C). This is also the reason oils tend to be highly viscous, since they are usually composed of long-chain hydrocarbons.
The half-life of this hydrophilic nonreactive isotope makes it suitable for geologic dating in the range of 60,000 to 1 million years. Additionally, large amounts of 36 Cl were produced by neutron irradiation of seawater during atmospheric detonations of nuclear weapons between 1952 and 1958.
Chloric acid, H Cl O 3, is an oxoacid of chlorine, and the formal precursor of chlorate salts. It is a strong acid ( p K a ≈ −2.7) and an oxidizing agent . Properties

Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]
