Well basically i dont know tbh
Evaporate the water.
copper sulphate is soluble.dissolve the two in water whereby cuso4 dissolves.filter the mixture the put the filtrate in an evaporating dish to evaporate excess water.do not evaporate to dryness coz some water ir required for crystalization.
no
You mix the whole lot in water, this means that the saline Potassium Sulphate dissolves into the water. Filter off the Potassium sulphate solution and all you have left is the water. Evaporate off the water and you should be able to see the remaining crystals of Potassium Sulphate on the bottom
you obtain salt from seawater by getting a container then let it sit out in the sun. By allowing it to sit out in the sun you will evaporate the water leaving the salt behind.
Evaporate the water.
1. Add water and stir. 2. Sodium chloride is dissolved. 3. Filter the liquid. 4. Sodium chloride passes the filter as a solution, without glass. 5. Evaporate the water to obtain NaCl as crystals. But the operation is useless because salt is very cheap.
If you leave the salt water in an evaporating basin the water will evaporate leaving you with big crystals of salt. To speed up the evaporating reaction you can heat it over a Bunsen Burner but your crystals of salt will the smaller.
A simple method is to filter the aqueous solution; after this the solution is heated to obtain crystallized KNO3.
Chalk (Calcium carbonate) is insoluble. Copper sulphate is soluble. To separate, first place the mixture in wter. The copper sulphate will dissolve, the chalk will not dissolve. When the copper sulphate is fully dissolved, filter the solution. The copper sulphate component will pass through the filter paper, but the chalk will remain in the filter paper. Dry the filter paper to obtain the dry chalk. Evaporate the solution to dryness, to obtain the blue dry copper sulphate crystals.
Sulfur is not soluble in water, sodium chloride yes. Filter the solution containing S and NaCl; sulfur remain on the filter, NaCl solution passes the filter. Evaporate te water by heating to obtain crystallized NaCl.
To obtain crystals from the reaction of magnesium and sulfuric acid, you can follow these steps: 1) Mix magnesium ribbon with diluted sulfuric acid in a beaker. 2) Allow the reaction to occur, which will produce hydrogen gas and magnesium sulfate. 3) Filter the mixture to remove any excess magnesium or impurities. 4) Evaporate the filtered solution to allow the magnesium sulfate to crystallize and form crystals.
You can obtain smaller and purer crystals by means of using precipitation or using the bigger crystals, because it is better to get them big, then cool them to make them small.
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

Add water and stirr: salt is soluble, sand not. Filter the solution. On the filter re- main sand, in the solution salt. After repetitive evaporations you can obtain salt as crystals.
Allow the water to evaporate, leaving behind the salt would be effective for separating salt and water in a mixture.
