Iodine can be separated by:
- extraction with an adequate solvent, for ex. hexane
- heating and evaporation
Iodine can be separated by:- extraction with an adequate solvent- heating and evaporation
first add water to mixture the ammonium chloride and barium chloride dissolve in the water but the iodine does not. filter out the iodine using filtration then use fractional crystallization to separate the ammonium chloride and barium chloride and water
Add sufficient water to dissolve the ammonium chloride. Neither the iodine nor the sand will dissolve.Filter out the solids.Evaporate the ammonium chloride from the solution.Heat the solids gently in a retort to sublimate the iodine and recover it.
Iodine can be extracted with ethanol.Sand is not soluble in water and can be separated by filtration from the water mixture.Sodium chloride remain in solution; heating the solution crystalline salt is obtained.
Iodine is not contained in Sodium Chloride, so can not be removed from it. I am thinking you wish to separate a mixture of Iodine and Sodium Chloride. Heat the mixture to 114C and the iodine will melt. Iodine can be vaporized and distilled. Under certain conditions, Iodine can react with other chemicals to create unstable explosive compounds. So be careful out there.
Because iodine has a number of chlorides so the name would be ambiguous.
Should be by sublimation. We make use of the fact that iodine sublimes(changes to solid to gas immediately) upon heating why potassium chloride does not :D
Iodine is well known to sublime (change from solid to gas without becoming liquid inbetween) when heated. However sodium chloride has a melting point much higher than that of iodine. Therefore, a mixture of iodine and sodium chloride can be separated by using a sublimation apparatus, with solid iodine collected by condensation on a cold surface.
iodine crystals are black, table salt crystals are white.however I doubt that was your question. I think you are referring to iodized table salt. there are no iodine crystals in iodized salt, instead they add sodium iodide to the table salt. sodium iodide crystals are indistinguishable visually from the sodium chloride crystals of table salt.the only practical way to separate sodium iodide from sodium chloride is the very tedious repetitive process of dissolving the mixed salts and performing fractional crystallization of the solution.
i think, perhaps cyrstalization or centrifugation.
first you take water in a beaker and put the mixture in it.you will see that ammonium chloride will dissolve in water because it is highly soluble in water and iodine is not so it won't dissolve. However, the solubility of elemental iodine in water can be increased by the addition of potassium iodide.you can then filter out the mixture so the iodine when you filter will stay on the filter paper. you have got your iodine separated.now for ammonium chloride, you can do evaporation or distillation. To get back water you can do distillation and get distilled water.
Iodine can be separated from salt by the process of sublimation.Sublimation is the process of conversion of a material from solid state to gaseous state without undergoing liquid state.Some sublimate objects are ammonium chloride,iodine,moth balls,camphor,etc.
