Which white powder turns blue-black in iodine solution?
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
What reaction happens when baby powder is mixed with iodine?
Baby powder, or talcum powder, is starchy in composition. When combined with iodine, the powder reaction will be a change in color to a dark blue, purple, or blackish hue depending on the amount used.
What is formed when calcium reacts with iodine?
When calcium reacts with iodine, calcium iodide is formed. This is a white crystalline solid that is soluble in water and has various industrial applications such as in the manufacturing of chemical compounds.
Is it tru that iodine reacts with starch to give a red color?
No when you but iodine with sarch for example a potato the starch reacrs with the iodine and it turns black
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.
How can you test if powder is talc or cornstarch?
One way to test if a powder is talc or cornstarch is by performing a iodine test. Mix the powder with iodine solution; if the mixture turns blue-black, it is likely cornstarch. Another way is to do a simple solubility test: dissolve the powder in water and if it is talc, it will not dissolve and settle to the bottom, while cornstarch will dissolve.

Why does iodine react with sugar?
Iodine reacts with sugar due to a chemical reaction called iodine starch reaction. Iodine forms a complex with starch molecules, giving a characteristic blue-black color. As sugar molecules can also form a complex with iodine, they can interfere with the reaction, leading to a color change.
