Dissolving salts in water can change the pH of the solution. Dissolving salts with acid residues from strong acids usually leads to neutral solutions. These salts include, but are not limited to, sodium sulfate, sodium chloride, and sodium acetate. | Sodium sulfate for exmple is used in detergents as a filler (thickening agent), in pulp production (sulfate process) and in the glass, textile and paint industries.
