Question
From the following data find the percentages of Na2CO3 and NaHCO3 in a mixture of these chemicals and inert constituents:
a) A 0.5000 g sample required 45.50 mL 0.1050 N HCl to reach the methyl orange end point.
b) 25.00 mL of 0.1000 N KOH is added to 0.2500 g of the sample; BaCl2 is added to precipitate the BaCO3 and 12.00 mL 0.1050 N HCl is required to reach the phenolphthalein end point.
