It is prepared by passing vapors of sulphur over red hot charcoal in iron or steel retorts at 750-1000 o C. ..

NaHCO 3 is made by saturating a solution of sodium carbonate with carbon dioxide. The white crystalline powder of sodium hydrogen carbonate being less soluble gets separated. On an industrial scale, sodium hydrogen carbonate (NaHCO 3 ) is obtained as an intermediate product in S..

By Heating any Ammonium Salt with an Alkali - In the laboratory, ammonia is usually prepared by heating a mixture of ammonium chloride and slaked lime in the ratio of 2 : 3 by mass. The arrangement of the apparatus is shown in the figure 6.2. As ammonia is lighter than..
