A 0.9092-g sample of wheat flour was analyzed by the Kjeldahl procedure. The ammonia formed was distilled into 50.00mL of 0.05063 M HCl; a 7.46-mL back-titration with 0.04917 M NaOH was required. Calculate the percentage of protein in the flour.
A second 25.00-mL aliquot was then treated with an excess of BaCl2 and 25.00 mL of the base; precipitation of all the carbonate resulted, and 7.63 mL of the HCl was required to titrate the excess base. Calculate the composition of the mixture.
