Iodine is used to test for unsaturated oils because it reacts with the carbon-carbon double bonds present in unsaturated fats. The iodine adds across the double bond, forming a colored complex with the unsaturated oil, which allows for easy detection of the presence of unsaturation in the oil.

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!
Why does iodine react with molecules in oils?
Since oil is a liquid. it can b known from that and from the known facts, oil has double bonds. no oil is completely saturated. the double bonds allow the iodine radicals to react to carbon molecules with double bonds in turn saturating the oil molecules. however the reaction takes place in a dark environment at boiling temperature and in presence of a suitable catalyst.
What is the chemical used to test for the presence of starch?
The chemical used to test for the presence of starch is iodine.
What is the principle behind the test for unsaturation in lipids?
This test identifies the level of saturation and the number of bonds a oil, fat or lipid has. The more unsaturated, multi-bonded, the lipid is, the more it absorbs iodine. The less iodine it absords, the lipid is considered to be saturated,single bonded.
What is I2KI used to test for?
I2KI (iodine/potassium iodide solution) is used to test for the presence of starch. In the presence of starch, the solution will turn blue-black due to the formation of a starch-iodine complex.
Why is bromine water used to test for unsaturated oils?

Significance of iodine value?
Iodine value is a measure of the degree of unsaturation in fats and oils, with higher values indicating greater unsaturation. It is used in the food industry to determine the quality and stability of fats and oils, as well as in the production of various products such as paints and varnishes. Additionally, iodine value can help assess the potential health impact of consuming fats with high unsaturation levels.
What happens when iodine is added to carbon?
Not a lot. If the carbon was part of an unsaturated fat, it may break double bonds to join the fat (this is a test for unsaturation; by measuring how much iodine is absorbed we know how unsaturated the fat is). Otherwise, iodine is quite unreactive when introduced to carbon.
What is the iodine test used to test for?
The iodine test is used to test for the presence of starch. Iodine solution interacts with the starch molecules, causing a color change from brownish-yellow to blue or black.
Why does iodine react with molecules in oils?
Since oil is a liquid. it can b known from that and from the known facts, oil has double bonds. no oil is completely saturated. the double bonds allow the iodine radicals to react to carbon molecules with double bonds in turn saturating the oil molecules. however the reaction takes place in a dark environment at boiling temperature and in presence of a suitable catalyst.
What is the chemical used to test for the presence of starch?
The chemical used to test for the presence of starch is iodine.
Can the iodine number of a blended oil be compared with the iodine number of the individual oils used?
yes, simple linear average
What does iodine detect?
The iodine test is used to test for starch. It reacts with starch to produce a purple blackish color.
What is iodine number?
Iodine number is a measure of the relative unsaturation of a substance, typically a fat or oil. It indicates the amount of iodine in grams that can be absorbed by 100 grams of the substance, with higher numbers indicating a higher degree of unsaturation. This value is useful in determining the quality and stability of fats and oils for various industrial and nutritional applications.
What is used to test for presence of polysaccharide?
Most likely the sucrose test. what biologist use is the iodine test. Iodine is used to test for the presence of starch( a polysaccharide) any material containing starch always turn blue-black when iodine is added.
What substance does Iodine test for?
Iodine is commonly used to test for the presence of starch. When iodine comes into contact with starch, it turns from its amber color to a blue-black color. This color change indicates the presence of starch.
What is the chermical you test for starch?
Iodine solution is commonly used to test for the presence of starch. When iodine solution is added to a substance containing starch, the mixture turns blue-black in color, indicating the presence of starch.
