Which compound is more soluble in water, ethanol or glycerol? And why?

Dear Student,

Based on Hydrogen bonding, glycerol will be more soluble in water. 
This is because glycerol contains three polar -OH groups which can form hydrogen bonds with water, while ethanol only has one -OH group.

Hope it helps.

A simple reason can be stated as: glycerol has three hydroxyl groups unlike one in ethanol. So it can be more soluble.
