How is washing soda synthesized ? |
|
Answer» All are copy paste natch Washing soda is synthesized through\xa0Solvay’s process.\xa0Solvay’s process involves the reaction of sodium chloride, ammonia and carbon dioxide in water. Carbon dioxide involved is produced through calcium carbonate and the calcium oxide left is used in recovering ammonia from\xa0ammonium chloride.At first, sodium bicarbonate is obtained which is then converted to sodium carbonate on heating. Finally, washing soda is produced by recrystallization of sodium carbonate.NaCl\xa0+\xa0NH3\xa0+\xa0CO2\xa0+\xa0H2O →\xa0NaHCO3\xa0+\xa0NH4Cl2\xa0NaHCO3\xa0→\xa0Na2CO3\xa0+\xa0H2O\xa0+\xa0CO2Na2CO3\xa0+ 10H2O →\xa0Na2CO3.10H2O soda is powder Washing soda is synthesized through\xa0Solvay’s process.\xa0Solvay’s process involves the reaction of sodium chloride, ammonia and carbon dioxide in water.

Sodium chloride(NaCl), ammonia( NH3) and carbon dioxide( CO2) are taken in water to form\xa0sodium bicarbonate( NaHCO3).2. Sodium bicarbonate is separated as it precipitates out from the solution as a solid. In presence of heat, it decomposes to form\xa0anhydrous sodium carbonate( soda ash).3.\xa0Recrystallization\xa0of the sodium carbonate obtained by dissolving in water.\xa0The process of formation of sodium carbonate is referred to as the Solvay process which is utilised to produce washing soda. |
