Ammonium Carbonate Used The Merseburg Process


Sciencemadness Discussion Board - Merseburg Process

Jul 09, 2012 · Not unlike a modified version of the Solvay Process, the Merseburg Process utilizes aqueous ammonium carbonate to precipitate an insoluble - or less soluble - carbonate precipitate, but instead of using sodium chloride as a feedstock, this process relies on the slight solubility of gypsum, in order to eventually precipitate out calcium carbonate, leaving behind an ammonium sulfate solution
