Which of the following mixtures can be separated by using the filteration method ?
a)Water and iron filings
b)Sugar and water
c)Soil and salt
d)Water and glucose
Answers
Answer:
only a) and c) can be separated using filtration.
Explanation:
a) Water and iron fillings can be separated using filtration method because the liquid water will pass away through the filter paper but the solid residue which is iron fillings will remain on the filter paper.
b) A mixture of sugar and water cannot be separated by filtration method of separation. This is because once you pour some sugar in water the sugar dissolves and disappears in the water. When you pour the sugar water through the filter paper, the water as well as the sugar both will pass through the filter paper.
c) Soil and salt can be separated by the filtration method because soil doesn't dissolve in water and its particles settle down at the bottom of the water and form a different layer. When you pour the soil water through the filter paper the water will pass through, but the soil will remain as a solid residue on the filter paper.
d) Water and glucose cant be separated by filtration because glucose dissolves in water and disappears in the water. So if we pass the glucose water through the filter paper the water and glucose both will pass through the filter paper and the glucose will not be obtained as a whole.
