This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.
It can be produced by heating K 2 SO 4 with carbon : K 2 SO 4 + 4 C → K 2 S + 4 CO. In the laboratory, pure K 2 S may be prepared by the reaction of potassium and sulfur in anhydrous ammonia. [4] Sulfide is highly basic, consequently K 2 S completely and irreversibly hydrolyzes in water according to the following equation: K 2 S + H 2 O → ...
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
K b (°C⋅kg/mol) Freezing point (°C) K f (°C⋅kg/mol) Data source; Aniline: 184.3 3.69 –5.96 –5.87 K b & K f [1] Lauric acid: 298.9 44 –3.9 Acetic acid: 1. ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Potassium silicate is the name for a family of inorganic compounds. The most common potassium silicate has the formula K 2 SiO 3, samples of which contain varying amounts of water. These are white solids or colorless solutions. [1]
Gallane liquid decomposes at 0 °C. Nitroxyl and diazene are simple nitrogen compounds known to be gases but they are too unstable and short lived to be condensed. Methanetellurol CH 3 TeH 25284-83-7 unstable at room temperature. [154] Sulfur pentafluoride isocyanide isomerises to sulfur pentafluoride cyanide. [155]
Intravenously, the LD 50 of potassium chloride is far smaller, at about 57.2 mg/kg to 66.7 mg/kg; this is found by dividing the lethal concentration of positive potassium ions (about 30 to 35 mg/kg) [37] by the proportion by mass of potassium ions in potassium chloride (about 0.52445 mg K + /mg KCl).
