The refractive index is about 1.55 at 1.0 µm. This reaction is important for the manufacture of silver bromide for photographic film: Aqueous bromide Br− also forms complexes when reacted with some metal halides such as copper(II) bromide: A traditional method for the manufacture of KBr is the reaction of potassium carbonate with an iron(III, II) bromide, Fe3Br8, made by treating scrap iron under water with excess bromine:[4], The anticonvulsant properties of potassium bromide were first noted by Sir Charles Locock at a meeting of the Royal Medical and Chirurgical Society in 1857.

The chemical formula KBr is an ionic compound (made from a metal and a non-metal). Due to its high solubility and hygroscopic nature it must be kept in a dry environment. Bromide compounds, especially sodium bromide, remained in over-the-counter sedatives and headache remedies (such as the original formulation of Bromo-Seltzer) in the US until 1975, when bromides were outlawed in all over-the-counter medicines, due to chronic toxicity. [6], There was not a better epilepsy drug until phenobarbital in 1912. [citation needed]. Compound: Moles: Weight, g: KBr: Elemental composition of KBr.

Potassium bromide is used in veterinary medicine to treat epilepsy in dogs, either as first-line treatment or in addition to phenobarbital, when seizures are not adequately controlled with phenobarbital alone. Parent Compound: CID 17690 (2-Bromoethyl(trimethyl)azanium) Component Compounds: CID 260 (Hydrogen bromide) CID 17690 (2-Bromoethyl(trimethyl)azanium) Dates: Modify . Potassium bromide (K Br) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US. Acne-form dermatitis and other forms of skin disease may also be seen, as well as mucous hypersecretion in the lungs. In infrared spectroscopy, samples are analyzed by grinding with powdered potassium bromide and pressing into a disc. K represents the metal potassium, and Br represents bromine (a non-metal halogen). It serves as a source of bromide ions. Potassium bromide tablets are sold under the brand name Dibro-Be mono (Rx-only). In high concentration, potassium bromide strongly irritates the gastric mucous membrane, causing nausea and sometimes vomiting (a typical effect of all soluble potassium salts). Adults who have reacted positively to the drug during childhood/adolescence may continue treatment. What is the rising action of faith love and dr lazaro? Molar mass of KBr is 119.0023 g/mol Compound name is potassium bromide Convert between KBr weight and moles. In Germany, it is still approved as an antiepileptic drug for humans, particularly children and adolescents. 1 Structures Expand this section.

It improves differentiation between exposed and unexposed crystals of silver halide, and thus reduces fog. As with other antiepileptics, sometimes even therapeutic doses (3 to 5 grams per day, taking 6 to 8 weeks to reach stable levels) may give rise to intoxication. KBR was awarded a $100 million contract in 2002 to build a new U.S. embassy in Kabul, Afghanistan, from the U.S. State Department.
