There are four mixtures A, B, C and D. The mixture A contains sand and sugar, mixture B contain chalk powder and salt, mixture C contains salt and sugar, whereas mixture D contains sugar and charcoal powder. Which one of these mixtures cannot be separated by using water as a solvent?
Answers
Answer:
I think sand and sugar
Explanation:
as sugar dissolves in water so cant seperate
Answer:
Mixture of sand and sugar, chalk powder and salt ,sugar and charcoal powder is a heterogeneous mixture in water.
Mixture of salt and sugar is homogeneous mixture in water.
When mixture of sand and sugar, chalk powder and salt ,sugar and charcoal powder are dissolved in water then they form heterogeneous mixture. So they can be separated using water as a solvent by filtration and evaporation method.
While when mixture of salt and sugar is dissolved in water they form homogeneous mixture. So they cannot be separated by using water because both will be dissolved in water and so they cannot be separated using filtration and evaporation.
They can be separated by using alcohal as a solvent in which sugar will be dissolved in water while salt cannot be. So they can be separated.
Final answer
Mixture of salt and sugar cannot be separated using water as a solvent because it form homogeneous mixture in water.
