A magnet can be used to separate a mixture of iodine crystals and iron filings. Since iron is magnetic, it will be attracted to the magnet, allowing it to be pulled away from the non-magnetic iodine crystals. Once the iron fillings are removed, the iodine can be collected separately.
Since lead iodide is insoluble in an aqueous solution, you could filter it out using a funnel and filter paper.
An iodine and ethanol mixture is homogeneous because iodine dissolves well in ethanol, forming a single-phase solution where the iodine molecules are evenly distributed throughout the ethanol. To separate the mixture, one can use methods such as evaporation, where heating the solution would cause the ethanol to evaporate, leaving behind the iodine. Alternatively, fractional distillation can be employed to separate the two components based on their differing boiling points.
Yes, iodized salt is considered a homogeneous mixture because the iodine is evenly distributed throughout the salt crystals, resulting in a consistent composition throughout the mixture.
When you mix sand and iodine, the iodine does not chemically react with the sand; instead, it simply forms a physical mixture. The iodine may give the sand a brownish or purplish color, depending on the amount of iodine used. However, the iodine remains as separate particles and does not dissolve in the sand. This mixture can be easily separated through physical means, such as filtration, since sand is a solid and iodine can sublime or be evaporated.
Iodine exists as I2. The crystal of iodine is formed simply by the interaction of iodine molecules as a result of Van de Waals forces, which allows for these molecules to bond together to form a solid.
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.
By heating it at low temperatures.

Yes, the sieving method can be used to separate iodine crystals and iron fillings. This method relies on the difference in particle size between the two substances to effectively separate them through a sieve or mesh screen. The smaller iodine crystals will pass through the sieve, while the larger iron fillings will be retained on top, allowing for separation.
To separate crystals of iodine and charcoal, we can utilize the process of sublimation. Iodine undergoes sublimation, where it transitions directly from a solid to a gas when heated, leaving behind the charcoal. By heating the mixture, the iodine crystals will sublimate and can be collected as a gas, while the charcoal remains behind.
Iodine crystals are a pure substance.
Iodine is a chemical element; not a mixture, not a compound.
Iodine crystals can be separated from diamond by using sublimation. Iodine can be sublimated at a low temperature, converting it from a solid to a gas without melting. This allows the iodine to be collected as a gas, leaving behind the diamond.

no.
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.
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.
