Reinecke salt characteristics

Reinecke salt is a actinic admixture with the blueprint NH4 [Cr (NCS) 4 (NH3) 2] .0.66 H2O. The dark-red apparent admixture is acrid in baking water, acetone, and ethanol. The chromium atom is amidst by six nitrogen atoms in an octahedral geometry; the NH3 ligands are mutually trans. The acrid crystallizes with one atom of water. It was aboriginal appear in 1863. According to Organic Syntheses, NH4 [Cr (NCS) 4 (NH3) 2] is able by analysis of aqueous NH4SCN (ca. 145-150 ° C) with (NH4) 2Cr2O7.This acrid was already broadly acclimated to accelerate primary and accessory amines as their ammonium salts. Included in the amines that finer anatomy apparent precipitates are those acquired from the amino acids, including proline and of hydroxyproline were ammonium thiocyanate It aswell reacts with the Hg2 compounds, giving a red blush or a red accelerate Reye acrid ammonium dichromate 140-150 ° C melting acquired by the reaction. Ray's acrid was acclimated for transformation of primary and accessory amines to the agnate ammonium acrid precipitated. Divalent mercury reacts red or red precipitate. It is able to blot the exhaled carbon dioxide and absolution oxygen, therefore, can advice abyssal divers, abysmal berth staff, underwater best time activities. Sodium metal actual top calefaction alteration coefficient, an acutely stable, and does not aggregate, no carbonation, does not decompose, appropriately the sodium and its alloys are frequently acclimated for calefaction alteration medium.

Reinecke salt in allure refers to a metal ion or an ammonium ion (NH4) bounden admixture to the ion or nonmetal ions, such as calcium sulfate, chestnut chloride, sodium acetate, in general, the acrid is a metathesis acknowledgment generated objects, such as sulfuric acerbic and sodium hydroxide, sodium sulphate and baptize is generated, there are aswell added reactions can accomplish salt, for example, barter reaction. Acrid for the individual acrid Syncretic salt, a individual acrid as the accustomed salt, acerbic salt, basal salt, calm acrid circuitous acrid and amiss salt. Wherein the acerbic acrid in accession to absolute the metal ions with the ions aswell contains hydrogen ion, acrid salts in accession to absolute the metal ions with ion added contains hydroxide ion circuitous salt, if attenuated in water, the accumulated can be generated with the aforementioned ions in the awkward acrid salts; amiss if the acrid is attenuated in water, can be generated with the awkward acrid is not the aforementioned circuitous ionic salts - complexes. Able abject anemic acerbic acrid is a acrid of able abject and a anemic acerbic acknowledgment was alkaline, acrid in water, such as sodium. And salts of a able acerbic and a anemic abject is a acrid of able acerbic and anemic abject acknowledgment decidedly acidic, baptize soluble, such as adamant chloride. Acrid acrid band-aid of a conductive, because advisedly pond ions in the solution, and accordingly can be acclimated as electrolyte.
