Sciencemadness Discussion Board Merseburg Process

09/07/2012· Merseburg Process In light of all of the copper sulfate and sulfuric acid synthesis question threads, I was thinking that a discussion of a kitchen-friendly version of the Merseburg Process (or rather, the Ammonium Carbonate-Gypsum Process) would be in order. Merseburg Process: (NH4)2CO3 + CaSO4 --> (NH4)2SO4 + CaCO3 Not unlike a modified version of the Solvay Process, the Merseburg Process

Ammonium carbonate Wikipedia

Ammonium carbonate is a salt with the chemical formula (NH 4) 2 CO 3. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and was a predecessor to the more modern leavening agents baking soda and baking powder. It is a component of what was formerly known as sal volatile and

Ammonium Carbonate Ammonium Carbonate

6. Ammonium carbonate and ammonium bicarbonate can be used (9,10) as blowing agents in the production of various types of foam rubber. Gases can be released by heating or adding acid. Ammonium carbonate was one of the earliest blowing agents used with polymers. It was first used on rubber 19th century England (11). It is added to the rubber

What is Ammonium Carbonate? Definition, Formulas,

Properties of Ammonium Carbonate. Ammonium Carbonate decomposes at 58 °C. Therefore, this temperature is its melting point. Being a water-soluble compound, it is highly soluble in water; When we expose it to air, this salt converts into white porous lumps or powder of ammonium bicarbonate due to loss of ammonia and carbon dioxide and becomes
