Description
Aluminium chloride, basic hydrate is an inorganic aluminium salt supplied at 25 % Al, with CAS number 12042-91-0, EG nr. 234-933-1 and empirical formula Al₂(OH)₅Cl · 2–3 H₂O. The hydrate has a density of 1,947 g/cm³ and is packed as 500 g in plastic, a format suited to laboratory weighing and routine handling. Basic aluminium chloride hydrate of this composition is used as a flocculation and precipitation agent, where the stated 25 % Al content defines the aluminium contribution in coagulation and related precipitation work. This 500 g plastic pack from manufacturer Carl ROTH presents the solid ready for laboratory handling according to the user’s method. With CAS number 12042-91-0 and EG nr. 234-933-1, the product can be identified unambiguously in specifications and inventory records. The empirical formula Al₂(OH)₅Cl · 2–3 H₂O describes a basic chloride with two to three waters of hydration, and the density of 1,947 g/cm³ supports handling calculations for the 500 g plastic pack.
