please HELP
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:)
You can separate water from alcohol by fractional distillation. By heating the mixture to the right temperature, the alcohol will evaporate and leave the water behind. However, alcohols and water are quite difficult to separate completely, and the separation will not be 100% by this method.
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.
Nothing will happen when you add water to chalk, because chalk does not dissolve in water. However, if you are drawing with chalk, as the water evaporates, it will allow the chalk to spread and create more fun.
Due to the chemical composition of Chalk, you can separate it from water either by filtration of evaporation.
Filtration would separate the water, leaving the chalk particles behind.
Filtration would separate the water, leaving the chalk particles behind.
Separation by filtration is a method.
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.
Filtration is used to separate chalk from water because chalk is insoluble in water. When the water containing chalk is passed through a filter, the chalk particles are trapped by the filter paper, while the water passes through, resulting in the separation of the two substances.
A foil does not separate chalk, sugar, and water because these substances are all able to mix and dissolve in water. Chalk is insoluble in water but sugar is soluble, so both can dissolve into the water without being separated by the foil barrier.
One way to separate chalk from water is through filtration. Pour the chalk-water mixture through filter paper in a funnel. The water will pass through, leaving the chalk behind on the filter paper.
To separate salt from chalk, you can dissolve the mixture in water. Salt is soluble in water while chalk is not. After dissolving, you can filter the mixture to separate the insoluble chalk from the salt solution. By evaporating the water from the salt solution, you can obtain the salt crystals.
To separate chalk from a mixture of chalk and copper sulfate solution, you can add water to dissolve the copper sulfate, leaving behind the chalk. The water-soluble copper sulfate will form a blue solution, allowing you to filter out the chalk residue, which is insoluble in water.
To separate the mixture of chalk powder, water, and stones, you can use a process called sedimentation followed by filtration. Allow the mixture to settle, as the stones will settle at the bottom due to their higher density. Then, carefully pour off the water to a separate container, leaving the stones behind. Finally, filter the remaining mixture to separate the chalk powder from the water.
Chalk particles can be collected by using a filtration process. A filter paper or a fine sieve can be used to separate the dissolved chalk particles from the water. The water can then be evaporated to obtain the solid chalk residue.
