Kaliumdichromat

Beschreibung:

Kaliumdichromat, mit der chemischen Formel K2Cr2O7 und der CAS-Nummer 7778-50-9, ist ein leuchtend orange-rotes kristallines Feststoff, das hochgradig in Wasser löslich ist. Es handelt sich um eine anorganische Verbindung, die als starkes Oxidationsmittel dient und häufig in verschiedenen Anwendungen eingesetzt wird, einschließlich analytischer Chemie, Färbung und als Korrosionsinhibitor. Die Verbindung ist bekannt für ihre Toxizität und krebserregenden Eigenschaften, was eine sorgfältige Handhabung und angemessene Sicherheitsmaßnahmen erfordert. Kaliumdichromat zeigt starke oxidierende Fähigkeiten, was es in Redoxreaktionen effektiv macht, und es kann mit einer Vielzahl von organischen und anorganischen Substanzen reagieren. Neben seinen industriellen Anwendungen wird es auch in Laborumgebungen für qualitative Analysen und als Reagenz verwendet. Aufgrund seiner gefährlichen Natur wird es als gefährliche Substanz eingestuft, und seine Verwendung ist in vielen Ländern reguliert, um Umwelt- und Gesundheitsrisiken zu minimieren. Eine ordnungsgemäße Entsorgung und die Einhaltung von Sicherheitsprotokollen sind unerlässlich, wenn man mit dieser Verbindung arbeitet.

Reagecon Potassium Dichromate 0.167M (1.0N) Analytical Volumetric Solution (AVL)

CAS: 7778-50-9

Reagecon's Potassium Dichromate 0.167M (1.0N) Analytical Volumetric Solution (AVL) is a fully factorised, high purity, stable product, developed and tested for oxidation/reduction titrations.  This Analytical Volumetric Solution, also called titrant, standard titrant or standard solution, is tested to a specification of ± 0.1%. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete.  The product may be used for manual titrations, or more commonly automatic titrations, to determine the end points by detection of any of several properties.  Oxidation/reduction titrations depend on changes in the electropotential of the oxidation reduction system and always involves a reaction between an oxidising and reducing pair. - Titration is a rapid, economical and versatile analytical tool. This Reagecon titrant is accurate, stable, reproducible and fully factorised. Titrations performed with this product, exhibit defined stoichiometry, are quantitative, establish an equilibrium that is definitive and fast and provide unambiguous results. Stability is proven (either opened or unopened) for the shelf life of this product.
