Question

What is deliquescence? a. When a hydrate first crystallizes c. When a hydrate become completely in soluble b. When water can sometimes continue to be added to a hydration shell until the material actually dissolves in the adsorbed water d. None of the above

Answer 1

Deliquescence is the process when a hydrate becomes completely soluble by absorbing water vapor from the air.

Step-by-step explanation:

Deliquescence is the process when a hydrate becomes completely soluble by absorbing water vapor from the air. This occurs when the vapor pressure of the water in the air is higher than the vapor pressure of the water being held in the hydrate. The absorbed water molecules form a hydration shell around the ions or molecules of the hydrate, causing it to dissolve.
