    Inorganic Acid

    Phosphoric Acid

    Phosphorous acid is used for reaction with inorganic and organic products, for water treatment, industrial and agricultural uses. It is also used to bleach industrial and cleaning supplies.

    Hydrofluoric Acid

    Hydrogen fluoride is a chemical compound with the chemical formula HF. This colorless gas or liquid is the principal industrial source of fluorine, often as an aqueous solution called hydrofluoric acid. It thus is the precursor to many important compounds including pharmaceuticals and polymers (e.g. Teflon). HF is widely used in the petrochemical industry as a component of superacids. Hydrogen fluoride boils near room temperature, much higher than other hydrogen halides. Unlike other hydrogen halides, HF is lighter than air.Hydrogen fluoride is a highly dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with moisture. The gas can also cause blindness by rapid destruction of the corneas.French chemist Edmond Frémy (1814–1894) is credited with discovering anhydrous hydrogen fluoride while trying to isolate fluorine, although Carl Wilhelm Scheele prepared hydrofluoric acid in large quantities in 1771, and this acid was known in the glass industry before then.

    Phosphorous Acid

    Phosphorous acid is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.

    Hydrochloric Acid

    In the production of chlorides, refining ore in the production of tin and tantalum, for the neutralization of basic systems, as laboratory reagent, hydrolyzing of starch and proteins in the preparation of various food products, pickling and cleaning of metal products, as catalyst and solvent in organic synthesis, for oil- and gas-well treatment, in removing scale from boilers and heat-exchange equipment, pharmaceutic aid (acidifier).

    Polyphosphoric Acids

    It is used in the synthesis of ofloxacin, flumequine and ketotifen and other pharmaceutical products. It is used as a catalyst in the petrochemical industry; it is used in organic synthesis and as a substitute for orthophosphoric acid.

    Hexafluorosilicic acid

    A 1-2% solution is used widely for sterilizing equipment in brewing and bottling establishments.Other concentrations are used in the electrolytic refining of lead, in electroplating, for hardening cement, crumbling lime or brick work, for the removal of lime from hides during the tanning process, to remove molds, as preservative for timber.

    Sulfuric Acid

    Sulfuric acid (alternative spelling sulphuric acid) is a highly corrosive strong mineral acid with the molecular formula H2SO4 and molecular weight 98.079 g/mol. It is a pungent-ethereal, colorless to slightly yellow viscous liquid that is soluble in water at all concentrations. Sometimes, it is dyed dark brown during production to alert people to its hazards. The historical name of this acid is oil of vitriol. Sulfuric acid is a diprotic acid and shows different properties depending upon its concentration. Its corrosiveness on other materials, like metals, living tissues or even stones, can be mainly ascribed to its strong acidic nature and, if concentrated, strong dehydrating and oxidizing properties. It is also hygroscopic, readily absorbing water vapour from the air. Sulfuric acid at a high concentration can cause very serious damage upon contact, since not only does it cause chemical burns via hydrolysis, but also secondary thermal burns through dehydration. It can lead to permanent blindness if splashed onto eyes and irreversible damage if swallowed. Sulfuric acid has a wide range of applications including in domestic acidic drain cleaners, as an electrolyte in lead-acid batteries and in various cleaning agents. It is also a central substance in the chemical industry. Principal uses include mineral processing, fertilizer manufacturing, oil refining, wastewater processing, and chemical synthesis. It is widely produced with different methods, such as contact process, wet sulfuric acid process, lead chamber process and some other methods.

    Hydriodic acid

    Reducing agent, manufacture of inorganic iodides, pharmaceuticals, disinfectants.The 57% acid is also used for analytical purposes, such as methoxyl determinations.

    Inorganic acid, also known as mineral acid, is a general term for acids in inorganic compounds. Inorganic acids are generally inorganic compounds that can dissociate hydrogen ions. A compound consisting of hydrogen and a non-metallic element or group. According to the composition, inorganic acids can be divided into oxyacids, anaerobic acids, complex acids, mixed acids, superacids, etc. According to the degree of dissociation, they can be divided into strong acids and weak acids, and according to the ionizable hydrogen ion The number is divided into monobasic acid, dibasic acid and polybasic acid.
