Hello guys, i would like to ask, except for starch or carbohydrates, what else could turn iodine blue black in color?
health company that says they are selling alkaline water which is an antioxidant
Iodine has a strong affinity for starch molecules, which are long chains of glucose molecules. When iodine comes into contact with starch, it forms a complex with the glucose chains, resulting in a blue black color.
Yes, some other substances that can cause iodine to turn blue black include glycogen, cellulose, and dextrin. These substances also have glucose molecules, which can form complexes with iodine.
Yes, the concentration of iodine and starch can affect the intensity of the blue black color. Temperature can also have an impact, as the reaction between iodine and starch is more rapid at higher temperatures.
This specific color change is due to the formation of a complex between iodine and starch. This complex absorbs certain wavelengths of light, resulting in the blue black color. Other substances may also form complexes with iodine, but they may result in different colors.
Yes, the reaction between iodine and starch is reversible. If the iodine is removed, the blue black color will disappear. This can be achieved by adding a reducing agent, such as vitamin C, which breaks apart the complex between iodine and starch.
