Hydrochloric acid is used for a large number of small-scale applications, such as leather processing, household cleaning, [35] and building construction. [7] Oil production may be stimulated by injecting hydrochloric acid into the rock formation of an oil well , dissolving a portion of the rock, and creating a large-pore structure.
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet ( MSDS ) for this chemical from a reliable source and follow its directions.
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.
Hydrochloric acid forms an azeotrope with boiling point 108.58 °C at 20.22 g HCl per 100 g solution; thus hydrochloric acid cannot be concentrated beyond this point by distillation. [ 47 ]
Tin(II) chloride also behaves as a weak Lewis acid, forming complexes with ligands such as chloride ion, for example: SnCl 2 + CsCl − → SnCl − 3. Like SnCl 2 (H 2 O), trichlorostannate (SnCl − 3) ion is pyramidal. Such complexes have a full octet. The lone pair of electrons in such complexes is available
An element–reaction–product table is used to find coefficients while balancing an equation representing a chemical reaction. Coefficients represent moles of a substance so that the number of atoms produced is equal to the number of atoms being reacted with. [1] This is the common setup: Element: all the elements that are in the reaction ...
Strontium chloride can be prepared by treating aqueous strontium hydroxide or strontium carbonate with hydrochloric acid: . Sr(OH) 2 + 2 HCl → SrCl 2 + 2 H 2 O Crystallization from cold aqueous solution gives the hexahydrate, SrCl 2 ·6H 2 O. Dehydration of this salt occurs in stages, commencing above 61 °C (142 °F).
Hydrolysis gives arsenous acid and hydrochloric acid: AsCl 3 + 3 H 2 O → As(OH) 3 + 3 HCl. Although AsCl 3 is less moisture sensitive than PCl 3, it still fumes in moist air. [10] AsCl 3 undergoes redistribution upon treatment with As 2 O 3 to give the inorganic polymer AsOCl. With chloride sources, AsCl 3 also forms salts containing the ...
