Apply the like dissolves like rule to predict which of the following liquids is miscible with water.

Question

Quizplus · Accepted Answer

The "like dissolves like" rule suggests that polar and ionic substances are miscible with other polar substances. Water is a polar molecule. Formic acid (HCHO₂) and glycerin (C₃H₅(OH)₃) are both polar due to their hydroxyl (OH) groups, making them miscible with water. Methyl ethyl ketone (C₄H₈O), while less polar than the other two, still has a polar carbonyl group, allowing for some degree of miscibility with water. Therefore, all the listed substances are miscible with water.
