Explain, s it ever acceptable to pour chemicals down the drain? Explain.Explanation / Answer
Ans 6 :
It will be much easier to seperate NaCl and sand mixture as compared to NaCl and sugar mixture. The mixture can be seperated on the principle of solubility.
The NaCl is soluble in water whereas sand is not. So the mixture can be dissolved in water , and then filtered to seperate out the sand. The filterate can then be dryed to give back NaCl.
But since NaCl and sugar are both soluble in water , it is difficult to seperate the mixture.
