Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
The viscosity of an aqueous solution can either increase or decrease with concentration depending on the solute and the range of concentration. For instance, the table below shows that viscosity increases monotonically with concentration for sodium chloride and calcium chloride , but decreases for potassium iodide and cesium chloride (the ...
Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar. Consequently, the molecule has a large dipole moment with a negative partial charge (δ−) at the chlorine atom ...
HCLTech. HCL Technologies Limited, doing business as HCLTech, [ 8] is an Indian multinational information technology (IT) consulting company headquartered in Noida. Founded by Shiv Nadar, it was spun out in 1991 when HCL entered into the software services business. The company has offices in 60 countries and over 225,000 employees.
Chloric acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Chloric acid, H Cl O 3, is an oxoacid of chlorine, and the formal precursor of chlorate salts. It is a strong acid ( p Ka ≈ −2.7) and an oxidizing agent .
The commercially most relevant field of application for HCl regeneration processes is the recovery of HCl from waste pickle liquors from carbon-steel pickling lines. Other applications include the production of metal oxides such as, but not limited, to Al 2 O 3 and MgO, as well as rare-earth oxides, by pyrohydrolysis of aqueous metal chloride or rare-earth chloride solutions.
Ringer's solution. Ringer's solution. Ringer's solution is a solution of several salts dissolved in water for the purpose of creating an isotonic solution relative to the body fluids of an animal. Ringer's solution typically contains sodium chloride, potassium chloride, calcium chloride and sodium bicarbonate, with the last used to balance the pH.
Litmus test. A solution of hydrochloric acid (HCl) in water will turn blue litmus paper red. A solution of the base sodium hydroxide (NaOH) in water will turn red litmus paper blue. If the acid and base solutions above are mixed in the right proportion, the resulting solution will cause neither red nor blue litmus paper to change color.
