If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.

As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
by adding bromine water to the compound. if it is unsaturated, the red colour of the bromine water will fade quickly. if it is saturated, then it will not fade.
Bromine, which is represented by the chemical symbol Br, is very corrosive with most other elements. The only element I could find it does not react with is water.
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
Not with water! Maybe with something else in the water? It only ionises when dissolved in the water to: K+ and Br- , but does not react with it. Dissolving is purely physical!
An unsaturated oil will decolorize bromine water.
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
they would react
