What is Lanthanum Chloride Heptahydrate？ The chemical formula of lanthanum chloride is LaCl3. Molecular weight 245.27. White crystal. Easy to deliquesce. The melting point is 860°C, the boiling point is higher than 1000°C, and the relative density is 3.84225. Very soluble in water (decomposed in hot water), ethanol and pyridine, insoluble in ether and benzene. It is easy to form a complex salt with alkaline hydroxide Chemicalbook. When heated with dry hydrogen iodide below its melting point, lanthanum iodide is formed. When it is mixed with sodium pyrophosphate solution, lanthanum hydrogen pyrophosphate precipitates. This precipitate dissolves when the solution is stirred, but after a few days, crystallizes into small, round white spherical crystals (trihydrate salt).
