How chlorine bleaches by oxidation?
Chlorine bleaches the organic compound by oxidation process.It reacts first in aqueous solution giving nascent oxygen then the nascent oxygen oxidize organic compound making it colourless.i.eH2O + cl2 gives 2Hcl + O (nascent oxygen)Organic compound + O (nascent oxygen) gives colourless organic compound
What sugar react with iodine solution?
Iodine solution typically reacts with polysaccharides, such as starch, to produce a blue-black color. This reaction occurs because iodine molecules fit into the helical structure of starch. Simple sugars, like glucose and sucrose, do not react with iodine and will not produce a color change. Therefore, it is primarily starch that is tested for using iodine solution in laboratory settings.
Why KI is to be added to prepare to prepare iodine solution?
Potassium iodide (KI) is added to prepare iodine solution because it helps dissolve iodine (I2) in water, increasing its solubility and stability. This results in a more concentrated solution that is easier to work with for various applications, such as in titrations or as an antiseptic.
What organic molecule does iodine test for?
They test for carbohydrates. The Iodine reagent tests for starch. The Benedict's reagent tests for small sugars. Most carbohydrates are are made of sugar, and starch is a type of carbohydrate.
What is formed when water and iodine crystals and aluminium powder is combined?
When water, iodine crystals, and aluminum powder are combined, a reaction occurs in which hydrogen gas is evolved and a purple solution is formed due to the reaction of iodine with water. The aluminum powder reacts with water to produce aluminum hydroxide and hydrogen gas.
What is the name of the compound formed when lead reacts with iodine?
The compound formed when lead reacts with iodine is lead(II) iodide, with the chemical formula PbI2.

What color gives if starch reacts with iodine?
When iodine reacts with starch, the solution will turn a brownish colour.
What effect the iodine solution have on a leaf?
Iodine solution can test for the presence of starch in a leaf. When iodine solution is applied to a leaf, it will turn blue-black in areas where starch is present. This is because iodine reacts with starch to form a bluish-black complex.
Aluminium and iodine compound?
Aluminium iodide is the compound formed when aluminium reacts with iodine. The chemical formula for aluminium iodide is AlI3. It is a solid compound that is highly soluble in water and has a white color.
What will happen to a leaf when you put iodine solution into it?
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
What compound does FeI3 make?
Iron (III) iodide is the compound formed when iron reacts with iodine. Its chemical formula is FeI3.
What happens when we drop iodine solution on carrot?
When iodine solution is dropped on a carrot, the iodine reacts with the starch molecules present in the carrot, causing a color change. If the carrot contains starch, it will turn blue-black in the presence of iodine solution, indicating the presence of starch in the carrot.
What is the iupac name for the organic that reacts with Br2?
They may be ethene, propene! ethyne, propyne and all the unsaturated hydrocarbons
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 colour does bleach and iodine turn to?
Bleach turns yellow when it reacts with iodine. Iodine itself turns from brown to a colorless solution when mixed with bleach.
Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
