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.
Sodium chloride is soluble in water.
first, add water to the mixture, barium chloride is soluble in water. then filter through and funnel and filter funnel. then add sodium sulphate, using the stove they will expand and separate. ( sodium cloride, and sand
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.
Sulfur is extracted with carbon disulfide.Put sand and NaCl in water; sand which is not soluble can be separated from sodium chloride by filtration.
Sulfur is S , a chemical element . Sodium chloride ( NaCl ) is the table salt , a chemical compound . Sand represents a mineral ; the composition
Iron filings removed magnetically. Water will dissolve sodium chloride and suspend sand. Sand can be filtered out of the solution, and salt reovered by evaporation of water. Naphthalene can be removed separately if necessary by solution of mixture in alcohol.
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.
NaCl, table salt, and ammonium chloride will both dissolve in water. Sand is only sparingly soluble in water. If you want to further separate ammonium chloride from sodium chloride, you will need to dry the resulting solution. The sodium chloride will precipitate out first. The ammonium chloride will remain in the supernatant and can be poured off leaving the sodium chloride crystals behind.
To separate iodine from sand, the mixture can be dissolved in water since iodine is soluble in it, while sand is not. Once the iodine is dissolved, the solution can be filtered, leaving the sand behind on the filter paper. The iodine can then be obtained by evaporating the water from the filtered solution.
You can use a combination of filtration and evaporation. First, use filtration to separate the sulfur from the sand. Then, dissolve the sodium chloride in water and use evaporation to recover the salt once the water has evaporated, leaving the sand behind.
1. Put the mixture in water and stir.2. Filter the suspension. Sodium chloride pass in the solution. After water evaporation crystallized NaCl is obtained.3. Add carbon disulfide on the material remained on the filter. Sulfur is dissolved and pass in the solution. Sand remain on the filter.
