chalk powder has calcium carbonate in it. calcium carbonate is a non soluble substance
it is easier to filter it,

First remove iron filings with a magnet. That leaves sand, salt and chalk dust. Add water which dissolves the salt, and filter leaving the sand and chalk dust on the filter paper. Put that back in water and add acid to dissolve the chalk dust (CaCO3) leaving the sand as a solid. Filter to obtain the sand. The chalk dust will now be in the acid as CO2 and H2O and the Ca salt of the acid.
please HELP
Yes, it is possible, the speed is depending on the granulometry.
First you mix both chalk and salt in water. From the solution that you get, you can filter the chalk out because it is non soluble in water. As for the salt, all there is to do is to just evaporate the water out.
We use filtration when we want to separate a solid and a liquid. e.g. chalk and water The residue left behind at the filter paper will be chalk in this case, for it is a solid:)
No, filter paper is not suitable for separating chalk powder. Chalk powder is insoluble in water, so it will not pass through the filter paper when mixed with water. To separate chalk powder from water, you can use techniques like sedimentation or decantation.
One way to separate powder chalk and sugar is by using a process called filtration. Mix the chalk and sugar with water to make a solution, then use a filter paper to separate the chalk particles from the sugar solution. The chalk particles will be left on the filter paper while the sugar solution passes through.
Separation by filtration is a method.
Use a magnet to remove the iron filings. Filter the remainder to separate the insoluble chalk powder from the water. Wash and dry the iron filings as they will be contaminated. Dry the chalk powder to remove traces of water.
Stir stones, chalk and water until the chalk is in suspension. Pour off the chalky water (repeat as required), leaving the heavier stones behind. Filter the chalky water to let clear water pass through, so leaving the chalk in the filter paper.
Well, isn't that just a happy little question! One way you can separate water and chalk powder is by using a process called filtration. You can pour the mixture through filter paper or a sieve, which will allow the water to pass through while trapping the chalk powder. Just remember, there are many ways to solve a problem, so don't be afraid to get creative and try different methods until you find what works best for you.

first, put the mixture in water . salt will dissolve and then allow chalk powder to settle down. Then try decantation.
Pass the mixture through filter paper. The salt water will pass through leaving the chalk behind in the filter paper.
Foil does not separate a mixture of chalk powder, sugar, and water because the physical properties of these substances are not effectively separated by the foil. Chalk powder and sugar are both soluble in water, meaning they dissolve and form a homogenous solution. The foil is not able to selectively separate the components of the mixture based on their solubility or other physical properties. To separate these substances effectively, techniques such as filtration or evaporation would be more appropriate.
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
A magnet will attract the iron leaving the coffee behind. It is also possible to separate them by flotation on water; add some detergent to the water to break the surface tension so the iron powder can sink while the coffee powder floats.
