Hey guys, i really have no idea about the answer to this question, i am asked the following : What difference in properties of sand, copper sulfate and water makes this experiement possible?Could you help me with this question pleasethanksbtw the experiment is filtering copper sulfate from sand and then boiling it to get copper sulfatethanks once again in advance!!
First thing you have to do is know that sand, water and copper sulphate are physically mixed, not chemically, so it's a mixture. Since sand is relatively larger in size than others, you use filtration to separate sand from water and copper sulphate. The residue will be the sand and the filtrate will be the mixture of water and copper sulphate. That done, then you take the water and copper sulphate mixture and heat it for a little while, in order to decrease the amount of water present as some of it will be evaporated due to heating. After that, the mixture is cooled and put into an evaporating dish, where it is left let the water evaporate off some more. A glass rod is used in order to know whether the crystallization point has been reached or not. If yes, then blue crystals of copper sulphate will form on the glass rod, and after a little while blue copper sulphate crystals will form in the dish.
