Question
A mixture of NaHCO3 and Na2CO3 has a mass of 2.52 g. When treated with HCl(aq). 661 mL of CO2 gas is liberated with a pressure of 735 mm Hg at 25 °C.
NaHCO3(aq) + HCl(aq) → NaCl(aq) + H2O(l) + CO2(g)
Na, CO, (aq) +2 HCl(aq) → 2 NaCl(aq) + H₂O(f) + CO2(g)
What is the weight percent of NaHCO3 and Na2CO3 in the mixture?
Weight percent of NaHCO3
=
96
Weight percent of Na2CO3
=
96
