| Be sure to answer all parts. Sulfuric acid is commonly used as an electrolyte in car batteries. Suppose you spill some on your garage floor. Before cleaning it up, you wisely decide to neutralize it with sodium bicarbonate (baking soda) from your kitchen. The reaction of sodium bicarbonate and sulfuric acid is 2NaHCO3(s) + H2SO4(aq) Na2SO4(aq) + 2CO2(g) + 2H2O(l) You estimate that your acid spill contains about 6.1 mol H2SO4. What mass of NaHCO3 do you need to neutralize the acid? |

Solution
From the stoichiometry of the reaction
1 mol of H2SO4 reacts with = 2 moles of NaHCO3
6.1 mol of H2SO4 reacts with = 2 x 6.1 = 12.2 moles of NaHCO3
Mass of NaHCO3 = moles x molecular weight
= 12.2 mol x 84 g/mol
= 1024.8 g
