THE SOLVAY PROCESS The Solvay process, also known as the ammonia-soda process, is an industrial method for producing sodium carbonate (Na2CO3), commonly called soda ash. It utilizes readily available and inexpensive materials: salt brine (sodium chloride solution) and limestone (calcium carbonate). The process involves several steps, including the use of ammonia to facilitate the reaction between the salt and limestone. DETAILS OF THE PROCESS: 1. Purification of Brine: Salt brine is purified to
