How do you separate a mixture of common salt and wax and sand to obtain a pure sample of each substance?

Each of the three substances have a trait that makes them unique from the other two. By using this trait, you can seeperate them from each other.
The wax, for example, has a low melting point. The salt will dissolve in water.
If you start by heating the wax-sand-salt mix, until it has liquefied, then put it into boiling water, the wax should float, the salt should dissolve, and the sand should sink. As long as you can mix the wax around enough in a semi-liquid state to get the salt and sand free, you should be good.

How do you separate a mixture of iodine salt and sand?
First heat the mixture; the iodine will sublime and turn to a vapor which can be collected. Then add water to the remaining salt/sand mixture; the salt will dissolve but the sand will not. Finally, evaporate the water to obtain the solid salt.
Give an example of an mixture and a compound?
compound you cants separate and misture you can separate ----------- A chemical compound can be separated in elements by a chemical or physico-chemical method: for example we can obtain Na and Cl from NaCl by electrolysis. A mixture can be separated in components by mechanical procedures; for example we can obtain iron from garbage by an electromagnetic method.
How do you separate the gold from a mixture of gold and iron powder and salt?
First add water to the mixture to dissolve the salt, then filter with filter paper to obtain the mixture of gold and iron. Proceed by using a strong enough magnet to extract the iron powder and you should be left with the Gold.....
How can you separate a mixture of acetone and a-naphthol?
1. Dissolve the mixture in water. Because naphtalene is very low soluble in water remain and NaCL is dissolved.Filter the liquid to obtain a water solution of NaCl. Heat to evaporate water and to obtain solid NaCl.Naphtalene remain on the filter.2. Heat the mixture over 220 0C; naphtalene will be evaporated.
Is hot coffee a mixture?
If you have added milk and/or sugar to your hot coffee, you will have to stir it well, in order to obtain a homogeneous mixture.
Why is separation done in water?
- To obtain the useful components from a mixture.- To remove the unwanted components from a mixture. - To separate 2 or more useful components from a mixture.
How can we obtain pure substances from a mixture?
A pure substance is a sample of matter, either an element or a compound, that consists of only one component with definite physical and chemical properties and a definite composition.Here's an example: Grape juice is a mixture, but not a pure substance because if you leave it out long enough, it will begin to separate. If you can think of a mixture that has the qualities of that definition, then answer is yes. If you were think about juice, the answer is no. Hope that helps!
What is the most common food substance from which cells obtain energy?
glucose
What separation method do you use to separate benzene from a mixture of benzene and methyl benzene?
since benzene has a very less boiling point , it will evaporate easily if the mixture is heated . Thus we can obtain the vapour and condense it to obtain solid benzene

Is ink a mixture or compound or a element?
Mixture. A compound is a single substance consisting of atoms bound together (for a very simple definition): water (H2O), Ammonia, etc. A mixture is a combination of coumpounds/elements that are physically, not chemicall combined. When you dissolve sugar in water, you have a sugar-water mixture, not a compound since you do not obtain a single substance "sugar-water" with a unique chemical formula.
How do you separate a mixture of sand and iodine?
First heat the mixture; the iodine will sublime and turn to a vapor which can be collected. Then add water to the remaining salt/sand mixture; the salt will dissolve but the sand will not. Finally, evaporate the water to obtain the solid salt.

Which method could be used to obtain copper from a mixture of powdered copper and sodium chloride?
Wash the mixture with water and separate the solid from the liquid, for example, by filtration. The sodium chloride will dissolve in the wash water, while the copper is left behind.
