what is solvey process

Feb 20, 2012The Solvay process is used to manufacture sodium carbonate Na 2 CO 3. The steps involved in this process are: 1. Purify saturated brine. 2. React it with gaseous ammonia. 3. The ammoniated brine is carbonated with CO 2 to form NaHCO 3. 4. This is insoluble in brine solution, so can be filtered out. 5. On heating, it decomposes to Na 2 CO 3. 6.
