No it turns purple.
Iodine turns blue when mixed with tap water because iodine forms a complex with starch in the presence of water, resulting in a blue-black color. This reaction is commonly used as an indicator for detecting the presence of starch in a solution.
Well, isn't that just a happy little accident! When you add iodine to sugar, it turns a dark purple or black color. It's like a beautiful, unexpected transformation right before your eyes. Just remember, every color has its place in the palette of life.
If you add Iodine-KI reagent to foods containing - starch such as bread, potato, crackers, or flour. A blue-black color results.If starch is not present, then the color will stay orange or yellow. (Iodine will not turn blue-black on contact with cellulose or disaccharides such as sucrose in sugar).Thus if you apply Iodine to an unripe fruit (where the sugars are still held as starch) the fruit will turn Blue-Black.However, once the fruit is ripe and the starch has been transformed into sweet sugar, the application of Iodine will only stain the fruit orange or yellow.
Yes, when a sugar is tested with an iodine solution, it can help determine the type of sugar present. Starch will typically turn blue-black in the presence of iodine, indicating its presence in the sample being tested. Other sugars like glucose or fructose will not react with iodine in the same way.
it is a yellowish/orange colour but when iodine is present, than it will turn an dark-blue/black colour
it does not turn blue when mixed with iodine. I don't think there is a colour change.
When sugar and iodine are mixed, the iodine will turn purple or black due to a reaction with the starch that is naturally present in sugar. This color change is commonly used as a simple test for the presence of starch.
No, apple juice will not turn blue-black when iodine is added. The blue-black color change indicates the presence of starch, which apple juice does not contain in significant amounts. Instead, the iodine will typically remain a brownish color when mixed with apple juice.
Iodine turns blue when mixed with tap water because iodine forms a complex with starch in the presence of water, resulting in a blue-black color. This reaction is commonly used as an indicator for detecting the presence of starch in a solution.
Starch turns blue-black when mixed with iodine because iodine molecules penetrate the starch molecules and form a complex compound. This complex shifts the wavelength of light absorbed by the mixture, resulting in the blue-black color. Alcohol can also form a complex with starch and iodine, leading to the same color change.
Iodine interacts with starch to form a blue-black complex. The amylase enzyme in saliva breaks down starch molecules into smaller sugar molecules, preventing the iodine from forming the blue-black complex. As a result, iodine does not turn blue in the presence of saliva and starch.
Adding iodine to the solution will turn it a deep blue which indicate presence of polysaccharides.

If a substance didn't turn blue or black with iodine, it means that it didn't form any complex with iodine. When iodine forms a complex with the substance, the complex is generally blue in color.
Because Iodine is a brown element.
