A B S T R A C T One object of present invention provides an aluminium sulphate com- position for use in such processes as the purifying of water, the sizing of paper and the dewatering of plants, which comprises a sloution of aluminium sulphate and polynuclear complexes therein of the formula Image where m and n are positive integers, having a pH of between about 3 and the highest pH, at which precipitation of aluminium hydroxide is substantial avoided and a method of producing the same. A further object of the invention relates to the use of an aluminium sulphate composition comprising a solution of aluminium sulphate and poly- nuclear complexes therein of the formula Image where m and n are positive integers, having a PH of between about 3 and the highest pH, at which precipitation of aluminium hydroxide is substantial avoided, in such processes as the purifying of water, the sizing of paper and the dewatering of plants. Another object of the invention provides a process for purifying water, sizing paper, dewatering plants and the like, which process is characterized by using in such a process a solution of aluminium sulphate and poly- nuclear complexes therein of the formula Image where m and n are positive integers, having a PH of between about 3 and the highest PH, at which precipitation of aluminium hydroxide is substantial avoided.
