Add warm water to dissolve the KBr which is very soluble. This would become the aqueous layer and would be more dense and thus at the bottom. Add them to a sep funnel and decant. Evaporate the water off and you have the KBr. The remaining fluid in the sep funnel is npahthalene
Put it in a beaker. Use a smaller beaker filled half way with ice and water and place in the larger one. It should be about and inch or two obove the mixture. Heat over a bunsen burner and the Naphthalene will deposit on the bottom of the smaller beaker.
suggest two method to separate a mixture of naphthalene and potassium chloride?
- naphthalene is soluble in chloroform
- potassium bromide is soluble in water
- sand is insoluble
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
Potassium will surround the Zn So it's name will be ZnCl2
Sand is a mixture of many different compounds, but the main component is Silicon dioxide, SiO2 .
heat the mixture until you no longer see white fumes, then stir the mixture to make sure all of the ammonium chloride is sublimed (solid moved to a gaseous state without passing through the liquid phase. All that should be left is the sand.
sulfur sodium chloride sand is a homogeneous mixture (solution)
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 way is to dissolve the ammonium chloride in water, then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity.
by sublimation
By evaporation (under vacuum) of the naphtalene or filtration of the sand from this mixture
Ammonium chloride is soluble in water and the sand can be separated from the solution by filtering.
Sodium chloride is soluble in water.
by sublimation
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
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.
Sand is made up of silicon dioxide and (table)salt is made up of sodium chloride. There are many types of salt (eg. potassium flouride, magnesium chloride), but they are mainly formed when a metal reacts with a halogen.
