How would you separate iodine crystals from mixture of iodine and sand?
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
How can iodine crystal be remove from the mixture?
Iodine crystals can be removed from a mixture by sublimation, where the crystals are heated to turn directly into vapour without melting. The vapour can then be condensed back into solid iodine crystals. This technique allows for the separation of iodine from other components in the mixture.
What dark crystals turn into purple vapour when they are heated?
Amethyst crystals are known to turn into purple vapour when they are heated. This phenomena is due to the presence of iron impurities in the crystal structure of amethyst that react to heat by creating the purple coloring.
How can crystal of iodine and charcoal could be separated?
Iodine and charcoal can be separated through sublimation, a process where iodine transitions directly from a solid to a gas without passing through the liquid phase. By heating the mixture, the iodine will sublimate, leaving behind the charcoal. The iodine gas can then be collected and cooled to form solid iodine crystals, effectively separating the two substances.
What colour should the leaf turn when iodine is added?
The leaf should turn blue-black when iodine is added, indicating the presence of starch.

How do you separate the mixture of crystals of iodine and charcoal?
By heating it at low temperatures.
What dark crystals turn into purple vapour when they are heated?
Amethyst crystals are known to turn into purple vapour when they are heated. This phenomena is due to the presence of iron impurities in the crystal structure of amethyst that react to heat by creating the purple coloring.
Its crystals sublime as violet gas iodine or bromine?
Sublimation is the process where a substance transitions from a solid directly into a gas without passing through the liquid phase. Iodine and bromine are examples of substances that undergo sublimation at room temperature, producing colored vapors. The solid crystals of these elements skip the melting phase and turn into vapor when heated.
What is iodine starch test?
It involves spraying the affected areas of the patient's body with a mixture of 500 g of water-soluble starch and 1 g iodine crystals. Areas of the skin producing sweat will turn black
What happens when you burn an iodine crystal?
when iodine crysatals are heated, they turn from a solid into a gas (vapour). They start a black colour and as they gradually turn into a gas, they turn to a purple colour. At the end, there are no crystals left.

Why does powdered sugar turn black in iodine?
it does not turn blue when mixed with iodine. I don't think there is a colour change.
Why does a sugar solution turn brown when Iodine is added?
Because Iodine is a brown element.
Does sugar turn blue when mixed with iodine?
Yes, sugar does not turn blue when mixed with iodine. Iodine reacts with starch, turning it into a blue-black color. Sugar does not contain starch, so it will not have a reaction with iodine in this way.
What would you say about a subtance if it did not turn blue-black with iodine?
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.
