The present disclosure provides a method of increasing the concentration of KO in an aqueous solution. The method comprises reacting potassium sulfate with an acidic compound to yield a product that includes potassium hydrogen sulfate. The product can be used to supplement crops in need of potassium. The product can also have other nutrients added to it, depending on the desired end use. Advantageously, these products increase yield as compared to prior art products.

Process of converting potassium sulfate to potassium hydrogen sulfate

Novel water softening products and methods of treating hard water are provided. The products comprise a salt and a metal chelating agent. The products are useful for regenerating ion exchange material in a water softening system and providing softened water containing both sodium and potassium ions, while having dramatically increased efficiencies over prior art products.

Water softening compositions

Water softening compositions and methods

Deicing compositions comprising magnesium chloride and potassium sulfate are provided. The compositions are pet friendly and have less of a detrimental impact on the environment and vegetation than prior art compositions. Methods of reducing or preventing the build-up of ice or snow on various surfaces are also provided.
