What else can I help you with?
What colour does bromine water change when you mix it with saturated fat?
Bromine water will change from orange to colourless when it is mixed with saturated fat.
What happens when bromine water is added to ethanol?
When bromine water is added to ethanol, the bromine will react with the ethanol forming 2-bromoethanol. The reaction occurs via nucleophilic substitution where the bromine reacts with the -OH group of ethanol. This reaction can be used as a test to distinguish between primary, secondary, and tertiary alcohols.
What evidence is there that bromine undregoes photodissociation?
Bromine undergoes photodissociation in the presence of light, typically in the ultraviolet range. This process can be observed by the change in color of the bromine solution from reddish-brown to colorless due to the formation of bromine radicals. Additionally, spectroscopic studies show characteristic absorption spectra associated with the photodissociation of bromine molecules.
Is The color of elemental bromine is orange-red a physical or chemical change?
The color change of elemental bromine from red to orange is a physical change. This is because the substance's chemical composition remains the same; only its physical appearance, in this case its color, is altered.
What color does bromine water change when you mix it with unsaturated fat?
Bromine water changes from orange to colorless when mixed with unsaturated fats due to the addition reaction that occurs between bromine and the double bonds in the unsaturated fats.
What happens when ethene is mixed with bromine water?
it goes from a browny orange to colourless
What happens if ethene is shaken with bromine water?
If ethene is shaken with bromine water, the orange color of bromine water will be decolorized due to the addition reaction of bromine to ethene. This reaction results in the formation of a colorless compound called 1,2-dibromoethane.
What colour does bromine water change when you mix it with saturated fat?
Bromine water will change from orange to colourless when it is mixed with saturated fat.
How can you distinguish between ethene and ethyne by means of a chemical reaction?
One way to distinguish between ethene and ethyne is by performing a bromine water test. Ethene will decolorize bromine water, turning it from orange to colorless, while ethyne will not react with bromine water. This test takes advantage of the unsaturation in ethene that allows it to quickly react with bromine.
What happens if you mix cooking oil with bromine water?
The bromine water turns from orange to colourless, as it is breaking the double bonds. When the oil becomes saturated, any more bromine water that is added will not turn colourless.
What happens when bromine water is added to ethanol?
When bromine water is added to ethanol, the bromine will react with the ethanol forming 2-bromoethanol. The reaction occurs via nucleophilic substitution where the bromine reacts with the -OH group of ethanol. This reaction can be used as a test to distinguish between primary, secondary, and tertiary alcohols.

What is the Use of everyday life in bromine?
it can be used to see if the hydrocarbon you have just cracked is an alkane or an alkene (it with turn orange to colourless if it is an alkene)
What happens when acetylene is bubbled through bromine water?
When acetylene is bubbled through bromine water, the unsaturated acetylene undergoes a reaction with bromine (a halogen) to form a dihalogenated compound, bromoethylene. This reaction is an addition reaction where two bromine atoms add across the carbon-carbon triple bond in acetylene to form the product. The bromine water, which is originally orange-brown in color, will decolorize as the reaction proceeds.
When alkenes react with bromine water what colour do they change to?
They turn from orange to colorless.
What can you see when bromine water is added to an unsaturated organic compound?
When bromine water is added to an unsaturated organic compound, the solution will turn from orange to colorless as the bromine reacts with the double bonds in the compound. This reaction is a test for unsaturation in organic molecules, as saturated compounds do not react with bromine water in the same way.
What decolorises bromine in the absence of sunlight?
Organic compounds called Alkenes turns Bromine to colourless from orange-ish without sunlight as a catalyst. Alkanes however require sunlight to react.
