WebSep 1, 2024 · The hydration number of carbohydrate molecules in their aqueous solution can be calculated using the formula (1) ... The decrease in the hydration numbers with increasing solute concentration is consistent with overlapping of the hydration spheres around the solute molecules, which is expected for the concentrations we used. WebHow do hydration spheres work? When there are many water molecules relative to solute molecules, as in an aqueous solution, these interactions lead to the formation of a three-dimensional sphere of water molecules, or hydration shell, around the solute. Hydration shells allow particles to be dispersed (spread out) evenly in water.
