The boiling point of water is 100°C. The boiling point of acetone is 56°C. Which statement about distilling a mixture
marysya [2.9K]

Answer:

Acetone will vaporize from the mixture before water.

Explanation:

You have mentioned that the bp of water is 100°C and the bp of acetone is 56°C.We know that in the distillation process of mixture the substance having low bp vaporizes,condenses and gets collected in the separete container before the one having high bp.So the one having high bp remains in the original container and that is water.

Thus, the second option is correct.
