Na2CO3 solution after absorbing CO2(g) controlled at pH ∼7–8 contains high dissolved inorganic carbon (DIC = HCO3− + CO2(aq)) concentration in water applicable to both open and closed systems and the pH is suitable for the growth. High DIC concentration was also found to enhance the...
7.Solvent extraction: The crushed trona ore is mixed with hot water and the resulting solution is extracted to obtain sodium carbonate. 8.Purification and drying: The obtained sodium carbonate solution is purified and then dried to obtain solid Na2CO3. Safety Precautions When handling Na2CO3, it ...
