Potassium bromide and sodium bromide were used as anticonvulsants and sedatives in the late 19th and early 20th centuries, but were gradually superseded by chloral hydrate and then by the barbiturates.[23] In the early years of the First World War, bromine compounds such as xylyl bromide were...
Bromide compounds used to be used as sedatives and anticonvulsants. Specifically, sodium bromide and potassium bromide were used in the 19th and 20th century until they were replaced by chloral hydrate, which was in turn replaced by barbituates and other drugs. The ancient royal purple dye call...
Using only the periodic table, arrange the following elements in order of increasing ionization energy: krypton, arsenic, gallium, potassium. (from the lowest to the highest.) If the electronegativity difference between the elements in compound NaX is...
The compounds yielding water-soluble free radicals are, themselves, often completely water-soluble. Examples are potassium persulphate and ammonium persulphate. But also compounds which are not completely water-soluble but yield water-soluble free radicals can be applied with very good results. Examples...
Bromine is a dark, reddish brown liquid at room temperature. Its properties are similar and intermediate to other halogens like fluorine, chlorine, and iodine. ... Bromine is a poor conductor of electricity. This isbecause it exists as a covalent compound of two bromine atoms with no free ...
