In this experiment you added hydrochloric acid to regenerate your final benzoic acid from sodium benzoate. What inorganic by-product is formed in this reaction? 3. When sodium bicarbonate (molar mass 84 g/mol) reacts with benzoic acid (122 g/mol), sodium benzoate (144 g/mol) is formed, along with water and carbon dioxide. If sodium benzoate is the desired product, what is the atom economy for this reaction? e a

Answer 1

2) HCl(aq) + C6H5COONa(aq) ---> C6H5COOH(aq) + NaCl(aq)

NaCl is inorganic byproduct

3) NaHCO3(aq) + C6H5COOH(aq) ----> C6H5COONa(aq) + CO2(g) + H2O(l)

M.wt= 84 g   M.wt = 122 g         Mwt = 144 g

Atom economy = mass of atoms in desired product / mass of atoms in reactanta*100

              = 144/(84+122)*100

              = 69.9%
