Imagine that sulfuric acid is spilled on a lab bench. It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. The sodium bicarbonate reacts with sulfuric acid as follows:
2NaHCO3 (s) + H2SO4 (aq) à Na2SO4 (aq) + 2H2O (l) + 2CO2 (g)
Sodium bicarbonate is added until the fizzing of CO2(g) stops. If 35 ml of 6.0 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
