Bromine as a disinfectant

A brominecontaining stick was developed in 1958, because of the risks of using fluid bromine. This stick exists of brominechlorinedimethylhydantoin (Dihalo, DMH).Both chlorine and bromine are attached to a nitrogen atom, which acts as an organic support. Applied to water, DHM is hydrolyzed and forms hypochlorous acid.

Potassium bromide

Potassium bromide (K Br) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with overthecounter use extending to 1975 in the US. Its action is due to the bromide ion (sodium bromide is equally effective). Potassium bromide is used as a veterinary drug, as an antiepileptic mediion for dogs.

Chemicals That Should Never Be Mixed

· While it may seem like chemistry is a good science to learn through experimentation, it's never a good idea to randomly mix together chemicals to see what you'll get. Household chemicals aren't any safer than lab chemicals. In particular, you should use care when dealing with cleaners and disinfectants, since these are common products that react with each other to yield nasty results.

ASSORTED REACTIONS OF THE HALOGENS

Bromine. If you pass bromine vapour over hot iron, a similar but slightly less vigorous reaction happens, this time producing iron(III) bromide. Anhydrous iron(III) bromide is usually produced as a reddishbrown solid. Again the iron has been oxidised to an oxidation state of +3. Iodine . The reaction between hot iron and iodine vapour only produces iron(II) iodide, and is much less vigorous ...

Testing for alkenes

cannot. This allows us to tell alkenes apart from alkanes using a simple chemical test. Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene.

Bromine

Bromine is a chemical element with the symbol Br and atomic number 35. It is the thirdlightest halogen, and is a fuming redbrown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826 ...

How to Use Bromine in Your Pool |

· Never mix either of these with chlorine or bromine in an open container. Add each directly to the pool water. Step 3 Add Bromine to Your Pool Water. Use two or three automated erosion feeders to add the bromine to the pool water. These are closed containers with water access vents around the bottom. The water enters and swirls around the bromine tablets to dissolve them. If you were already ...

The Chemistry of the Halogens

Bromine (Br 2) is a reddishorange liquid with an unpleasant, choking odor. The name of the element, ... Finally, in 1886 Henri Moissan successfully isolated F 2 gas from the electrolysis of a mixed salt of KF and HF and noted that crystals of silicon burst into flame when mixed with this gas. Electrolysis of KHF 2 is still used to prepare fluorine today, as shown in the figure below ...

The Reactions of Alkanes,

Solutions of bromine in CCl 4 have an intense redorange color. When Br 2 in CCl 4 is mixed with a sample of an alkane, no change is initially observed. When it is mixed with an alkene or alkyne, the color of Br 2 rapidly disappears. The reaction between 2butene and bromine to form 2,3dibromobutane is just one example of the addition reactions of alkenes and alkynes. Hydrogen bromide (HBr ...

Why does bromine water decolourise when it reacts with ...

Answer (1 of 6): Bromine water has a distinctive brown colour. Saturated: Containing only single carbontocarbon bonds. Unsaturated: Containing at least one double carbontocarbon bond. Alkenes react spontaneously with bromine water due to their unsaturated nature. The reaction between ...

Changing of iron(II) ions to iron(III) ions and vice versa ...

· Bromine water oxidises iron(II) ions, Fe 2+ to iron(III) ions, Fe 3+. The presence of Fe 3+ ions is confirmed by the formation of brown precipitate with sodium hydroxide solution. Fe 2+ ions lose their electrons and are oxidised to Fe 3+ ions. Bromine molecules, which give the bromine water its brown colour, gain the electrons and are reduced to colourless bromide ions, Br –. This explains ...
