In the solid these water molecules also called waters of hydration are part of the structure of the compound.
Chromium iii chloride hexahydrate. ChromiumIII chloride also called chromic chloride describes any of several compounds of with the formula CrCl 3 x H 2 O where x can be 0 5 and 6. The anhydrous compound with the formula CrCl 3 is a violet solid. The most common form of the trichloride is the dark green hexahydrate CrCl 3 6H 2 OChromium chlorides find use as catalysts and as precursors to dyes for wool.
Hydrated ionic compounds ie hydrates have a specfic number of water molecules in their chemical formulas. In the solid these water molecules also called waters of hydration are part of the structure of the compound. Magnesium chloride is the name for the chemical compound with the formula MgCl 2 and its various hydrates MgCl 2 H 2 O xAnhydrous MgCl 2 contains 255 elemental magnesium by mass.
These salts are typical ionic halides being highly soluble in waterThe hydrated magnesium chloride can be extracted from brine or sea waterIn North America magnesium chloride is produced primarily from Great. During my early chemical investigations I acquired some chromiumIII chloride hexahydrate a green salt that gave an equally green solution when dissolved in water. Our product line consists of chemical solutions prepared to exact quality standards and certified for use in laboratories and production processes.
