Crystalline compounds that retain water during evaporation are referred to as being hydrated or are said to contain water of hydration. the crystal structure. For example, in the hydrated compound copper (II) sulfate pentahydrate (CuSO4(5H2O), the ratio is Hydrated crystals Hydrates are compounds that incorporate water molecules in their crystalline structures. The ratio of moles of water to one mole of that compounds is a small whole number. often incorporated in the formation of crystals from aqueous solutions. In chemistry, water(s) of crystallization or water(s) of hydration are water molecules that are present inside crystals. Percentage of water = Mass of water lost x Mass of hydrate. Hydrate Anhydride + Water CaSO 4 • 2H 2O CaSO 4(s) + 2 H 2O(g) Therefore, you can determine the percentage of water in a hydrate by determining the mass lost (amount of water driven off) when a known mass of hydrate is heated. Examples of hydrates are CaSO 4 • 2H 2 O Calcium sulfate dihydrate CoCl 2 • 6H 2. The formula of a hydrate consists of the formula of the anhydrous (without water) compound followed by a dot, then the number of molecules of water that crystallize with one formula unit of the compound, then the formula of water.
