Abstract
ABSTRACT
Fractional crystallization of lake salt (kanwa) was carried out
by concentrating and cooling its aqueous solution. The crystallized
fractions showed higher carbonate-bicarbonate ratio than the raw
samples. Controlled acid conversion of the carbonate present in the
lake salt to the bicarbonate was carried out in solution and solid
product obtained by crystallization. Products containing up to
08.44 ± 1.05% bicarbonate were obtained when hydrochloric acid was
used and up to 74.95 ± 1.39% when ethanoic acid was used.
Baking powder was formulated using the isolated sodium
bicarbonate. The baking powder when in contact with water behaved
in a similar manner to a commercial baking powder. The formulated
baking powder was also used in baking and the baked products were
also found to be very similar to those obtained with the commercial
baking powder.
