Organic Chemistry
A sample containing 25.14 g of neutral salts, glucose and a sodium carbonate/bicarbonate
buffer was dissolved in 100 ml of water. A 25 ml aliquot of the resultant solution required
20.35 ml of 0.0987 M HCl when titrated to the PP end-point. A second 25 ml aliquot was
titrated to the MO end-point and required 56.75 ml of the acid. Calculate the percentage of
Na2CO3 (molecular weight 106) and NaHCO3 (molecular weight 84) in the sample
