Introduction and Applications of Palladium chloride

Palladium chloride, is the chemical compounds with the formula PdCl2. PdCl2 is a common starting material in palladium chemistry – palladium-based catalysts are of particular value in organic synthesis. It is prepared by chlorination of palladium. Analysis Note Used as a catalyst together with Cu(II…

About metal

A metal is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable — that is, they can be hammered or pressed permanently out of shape without breaking or cracking — as well as fusible (able t…

Application of Metal products

Metal (carbide)–carbon eutectic fixed points when applied to radiometry should operate at a temperature preferably exceeding 3000 K, have a large aperture, be robust and have long plateau duration. The large-tube-diameter BB3500YY furnace, recently introduced at the National Metrology Institute of J…

Why is this medication prescribed?

Arsenic trioxide is used to treat acute promyelocytic leukemia (APL; a type of cancer in which there are too many immature blood cells in the blood and bone marrow) in people who have not been helped by other types of chemotherapy or whose condition has improved but then worsened following treatment…

Why is dimethylmercury toxic?

Dimethylmercury is one of the most potent neurotoxins known. It readily crosses the blood-brain barrier, probably due to its formation of a methylmercury-cysteine complex. It causes ataxia (lack of coordination), sensory disturbance and changes in mental state. It inhibits several stages of neurotra…

The products may be, the situation further reactions (such as combustion in air). Chemical reduction of materials in this group can quic…

Tungsten Trioxide

Tungsten trioxide is nearly exclusively created by calcination of APT under oxidising conditions. is probably the most crucial, highly pure intermediates for making other tungsten compounds including tungsten metal powder. From the latter application, it had been substituted to some large extent by…

What are the characteristics of sodium hypochlorite?

As a bleaching agent for domestic use it usually contains 5% sodium hypochlorite (with a pH of around 11, it is irritating). These characteristics must be kept in mind during transport, storage and use of sodium hypochlorite.Sodium hypochlorite is a clear, slightly yellowish solution with a characte…
