Filtration would separate the water, leaving the chalk particles behind.
Due to the chemical composition of Chalk, you can separate it from water either by filtration of evaporation.
Separation by filtration is a method.
As with separating salt from a salty solution of water by evaporation, so, with a chalky solution, you would boil off the water, leaving the chalk behind.
Filtration is the simplest method.
Assuming both the chalk and copper sulfate are solids, if you add water, the copper sulfate will dissolve and the chalk will not.
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.
The chalk powder would separate from the water and come to rest on the bottom of the container.
You can add water to this mixture, which will dissolve the salt but not the chalk. Decant the water, then boil it away, and you will be left with salt.Salt is much more soluble in water than chalk is.
Put it in water, salt goes down and chalk floats.
Because chalk(CaCO3) is insoluble in water and more over if you pass the mixture through a filter paper the chalk is left behind on the paper while the water seeps through it .
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.
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.
I would think you could pour it into a dish and allow the water to evaporate.
Salt is soluble in water, chalk is (pretty much) not. That should give you some ideas.
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.
