Solution Verified by TopprChlorine is more reactive than bromine and iodine. Thus, it displaces bromine from potassium bromide and iodine from potassium iodide. The presence of free bromine ions in the solution makes it appear red, and the presence of free iodine ions in ...

Thionyl - bis - monobrom - a - naphthol is prepared by adding a chloroform solution of bromine to a chloroform solution of thionyl-a -naphthol. According to the Provisional Specification, the coupling function occurs at least twice, and at least two naphthol residues, substituted or un...
In a flask, colourless N(2)O(4) is in equilibrium with brown-coloured NO(2). At equilibrium, when the flask is heated to 100^(@)C the brown colour deepens and
Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral halide salts, analogous to table salt. Čisti brom se ne nalazi u prirodi, već uglavnom u vidu bezbojnih, rastvorljivih kristalnih halidnih mineralih soli, analog...
Area developed salt pan of the construction of the more than 120 acres, an annual output of 500 tons of high quality for our more than 500, 1/10 of the total, bromide production capacity of 26000 tons, make up about a quarter of the country, ...
