Potassium Dichromate CAS 7778-50-9 AR, Assay 99.8%

Potassium Dichromate (CAS: 7778-50-9) has strong oxidation and corrosion, and can be mixed with reducing agent, organic matter, combustible material or metal powder to form explosive mixture, which can cause combustion or explosion by friction, vibration or impact.  
Potassium Dichromate, decomposes to release oxygen at white heat temperature, has strong oxidation, it is a toxic and carcinogenic strong oxidizing agent. It is classified as a group I carcinogen by the International Agency for Research on Cancer (IARC) and may catch fire when exposed to combustibles. Because Potassium Dichromate has strong oxidizing properties under acidic conditions, it is commonly used in the laboratory to prepare chromic acid wash solution (a mixture of saturated potassium dichromate solution and concentrated sulfuric acid) to wash chemical glassware to remove reducing dirt from the walls of the vessel. After use, the lotion changes from dark red to green, and the lotion will be ineffective. Potassium dichromate is also used in analytical chemistry, commonly used for quantitative determination of reductive hydrogen sulfuric acid, sulfurous acid, ferrous ion and so on. In heating, potassium dichromate can also oxidize concentrated hydrochloric acid, the release of chlorine.  
Used in the production of chrome alum, Chromium Oxide Green, chrome yellow pigment, electrode, printing ink, also used as tanning agent, enamel colorant, printing and Dyeing mordant used in the production of chrome alum, chrome oxide green, chrome yellow pigment. Enamel industry with its long powder, quartz sand and other mixed calcined enamel powder, as a green colorant. For the preparation of matches Medicine Head, from the role of oxidation and moisture. Used as a tanning agent for light leather. Mordant dyeing and printing are used as mordant. Synthetic fragrances were prepared for use as oxidants. Used for welding electrode, printing ink, metal passivation. Used as oxidants and catalysts in organic synthesis and raw materials for pharmaceuticals.
Used in the manufacture of chromium chemicals, mordant, ink, glass, perfume, pigment, ceramics, varnish, explosives, pharmaceuticals, etc.
