Question

Sodium carbonate is a reagent that may be used to standardiseacids in the same way that you have used KHP in this experiment. Insuch a standardization it was found that a 0.498g sample of sodiumcarbonate required 23.5mL of a sulfuric acid solution to reach theend point for the reaction Na2CO+HSO4----H2O+CO2+Na2SO4 What is the molarity of the H2SO4 Sodium carbonate is a reagent that may be used to standardiseacids in the same way that you have used KHP in this experiment. Insuch a standardization it was found that a 0.498g sample of sodiumcarbonate required 23.5mL of a sulfuric acid solution to reach theend point for the reaction Na2CO+HSO4----H2O+CO2+Na2SO4 What is the molarity of the H2SO4

Explanation / Answer

mol of NA2CO = mass / molar mass                         = (0.498 g) / (105.99 g/mol)                         = .0047 mol mol of NA2CO = mol of H2SO4 molarity of H2SO4 = mol / L                              = (.0047 mol) / (.0235 L)                              = 0.2 mol/L
