dc.description.abstractSodium hydrogen carbonate is used extensively in the baking and pharmaceutical industries, where it is required in very high purity. Commercially, it is prepared through the solvay process. " In this project methods of preparing high purity grade sodium hydrogen carbonate from Magadi soda have been investigated .The method studied involves the carbonation of soda ash at varying temperatures, pressures and stirring times. Determinations of sodium carbonate and sodium hydrogen carbonate concentrations were carried out titrimetrically using methyl orange-indigo carmine and thymol blue-cresol red mixed indicators at pH 3.8 and pH 8.3 respectively.en
