The loss in mass seen in this experiment therefore represents the water of crystallization that this sample contained. The mass of water that this hydrated salt contained is therefore 4.97 grams subtract 2.74 grams, which equals 2.23 grams of water of crystallization. The molar mass for water is 18 grams per mole.

WebApr 13, 2024 · In Na + sample, water evaporated from the solution, leaving behind the salt crystals deposits on the face of the shale sample. When Mg 2+ was investigated a surprising result was perceived. The water in the salt solution found it difficult to vaporize, and it remained in the shale sample even after 30 days. WebMar 5, 2024 · The solution is allowed to stand until crystallization is complete. Typical problems: Crystallization can be a slow process, and impatience can lead to low recovery. The solution is placed in an ice-water bath to lower the temperature even further, and allow more crystals to form. At this point, most crystals should already have formed.
A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures.
