49、ies Aluminium chloride anhydrous will react in water. Aluminium chloride basic, dialuminium chloride pentahydroxide and aluminium chloride hydroxide sulfate hydrolyse are acidic liquids which hydrolyse and form a precipitate of aluminium hydroxide when diluted beyond a particular level. Since aluminium compounds are amphoteric in nature, the solubility of aluminium depends on the pH value and the products should be used within an appropriate pH range. NOTE A characteristic of these products is their high t
