Appearance: White crystalline solid, easily dissolves in water.
Solubility: Highly soluble in water, hydrolyzes to form acidic solutions.
Stability: Less reactive as a Lewis acid than anhydrous aluminium chloride, thus not suitable for Friedel-Crafts catalysis.
Applications
Water Treatment: Functions as a flocculant in drinking water purification, aiding removal of suspended particles.
Textile Mordant: Used to fix dyes to fabrics in textile processing.
Cosmetics: Applied as an astringent in antiperspirants and skin-care products for moisture control.
Chemical Synthesis: Sometimes used as a reagent, though less common than the anhydrous form.
Pharmaceuticals: Occasionally used in drug delivery systems to improve the stability or availability of certain medications.
Hydrated aluminium chloride is less hazardous and easier to handle than the anhydrous form, making it suitable for diverse industrial and commercial applications.
