When bromine water is added to oil, if the oil contains unsaturated bonds, the reddish-brown color of the bromine water will be reduced as the bromine molecules add across the double bonds in a chemical reaction called bromination. This reaction is used to test for the presence of unsaturation in organic compounds like alkenes or alkynes.

Will saturated oils decolourise bromine?
Yes, saturated oils like coconut oil or palm oil will decolourize bromine because the double bonds in unsaturated oils are required for the bromine addition reaction that causes discolouration. Saturated oils lack these double bonds, so they will not react with bromine in the same way.
How is bromine used in everyday life?
One of the things bromine is used for is photographic film (used in camera)Bromine is also used as water purification, making engines in cars run better, and are also on rare occations bromine used as a pesticide.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
Fact about bromine?
Bromine is a reddish-brown liquid at room temperature and is the only non-metallic element that is liquid under normal conditions. It is known for its distinct smell, toxicity, and use in flame retardants, pharmaceuticals, and dyes. Bromine is also commonly used in the production of agricultural chemicals and in oil and gas drilling operations.
What is the chemical reaction for oil and water?
Oil and water do not react chemically; they are immiscible due to differences in polarity. Oil is nonpolar and water is polar, so they do not mix and form separate layers instead.
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 1 drop of bromine is added to vegetable oil?
When 1 drop of bromine is added to vegetable oil, a chemical reaction occurs where the bromine reacts with the unsaturated fats in the oil. This reaction causes the bromine to decolorize, turning from reddish-brown to colorless. This change is a test for the presence of unsaturated fats in the vegetable oil.
What happens when oil is added to water then frozen?
The oil ends up under the frozen water.
What happens when baking soda is added to oil with water?
The baking soda dissolves in the water
How do you know unsaturated fat is in vegetable oil?
An unsaturated oil will decolorize bromine water.
What happens to the density when corn oil is poured into water?
Water has a fixed density (depending on temperature), and it is more dense than corn oil by a little bit. If corn oil is added to water, the density of the mixture will decrease. This applies to "room temperature" water and oil. No one should be pouring hot oil into water.
Why does bromine water turn clear with rapeseed?
Rapeseed oil contains unsaturated fatty acids that react with bromine to form colorless products, causing the bromine water to turn clear. This reaction is known as a bromine test, which is used to detect the presence of unsaturation in organic compounds.
When Sudan 3 solution is added to palm oil what happens?
The oil become colored.
Motto for an oil-well-drilling company?
a drill
What will happen if olive oil is added to water?
the olive oil will form into droplets and not mix with the water
Why is bromine water used to test for unsaturated oils?
Bromine water is used to test for unsaturated oils because unsaturated oils can decolorize bromine water. The double bonds in unsaturated oils react with bromine, which causes the orange-brown color of the bromine water to fade. This color change is a characteristic reaction of unsaturated compounds.
Give a test to differentiate between butter and cooking oil?
there can be two explanation: 1. cooking oil is unsaturated while butter is saturated so buter can not be hydrogenated but cooking oil can be. 2. as we know that brown colour of bromine disappears when a drop of bromine is added to unsaturated compound whereas there is no reaction between saturated hydrocarbons.
