A study for the manufacture of sodium hydrogen carbonate
Abstract
Sodium 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.
