Question

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 2NaHC03(s) + H_2S04(aq) right arrow Na_2S04(aq ) + 2C02(g) + 2H_20(l) You estimate that your acid spill contains about 5.8 mol H_2S04- What mass of N'aHC03 do vou need to neutralize the acid?

Explanation / Answer

From the balanced equation, it can be seen that it takes TWO moles NaHCO3 to neutralize ONE mole of H2SO4. So, find moles H2SO4 and multiply by 2 to get moles NaHCO3 and then convert to mass.
moles of H2SO4 = 5.8 mol/L
moles of NaHCO3 needed = 2 x 5.8 = 11.6 moles
mass of NaHCO3 needed = 11.6 moles x 84 g/mol = 974.4 grams = 9.744 * 102 g of NaHCO3
