GRAVIMETRIC ANALYSIS OF A TWO COMPONENT MIXTURE

A mixture of NaHCO₃ and Na₂CO₃ reacts with hydrochloric acid solution to produce three common products, sodium chloride, carbon dioxide and water according to the following balanced chemical equations.

NaHCO_3(s) + HCl _(aq) → NaCl_(s) + CO_2(g) + H₂O_(l) (1)

Na₂CO_3(s)+ 2HCl_(aq) → 2NaCl_(s) + CO_2(g)+ H₂O_(l) (2)

Mass of mixture (gr) = mass (gr) of NaHCO₃ + mass (gr) of Na₂CO₃ (3)

Mass of NaCl (gr) = mass (gr) of NaCl formed + mass (gr) of NaCl formed (4)

from the NaHCO₃ from the Na₂CO₃

NOTE!!! Fill-out the tabulation below. Present the complete solution for the determination of the unknown amounts.

Mass of unknown mixture (g)
0.5000 g
Mass of NaCl formed (g)
0.4100 g
Mass of Na,CO; in mixture (g)
Mass of NaHCO, in mixture (g)
% Na,CO3
