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.

Why does bromine water turn clear with rapeseed?

Why is bromine water used to test for unsaturated oils?

As it causes a colourless reaction when you add both the bromine water and the oil you're testing for unsaturation. you can also use iodine water - it'll do exactly the same thing; BE CAREFUL though as both solutions are very hazardous. hope this helped!


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.
