1. TITRATION PROBLEM:

Oxalic acid is a diprotic acid. Calculate the percent of oxalic acid (H2C2O4) in a solid given that a 0.7984 gram sample of that solid required 37.98 mL of 0.2283 M NaOH for neutralization. Show your work!

2. TITRATION PROBLEM:

Some sulfuric acid is spilled on a lab bench. You can neutralize the acid by sprinkling sodium bicarbonate on it and then mopping up the resultant solution.

2 NaHCO3(s) + H2SO4(aq) --> Na2SO4(aq) + 2 CO2(g) + 2 H2O(l)

Sodium bicarbonate is added until the fizzing due to the formation of CO2(g) stops. If 27 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? Show your work!

Sodium Bicarbonate is used to neutrailze acids to form sodium chloride, a salt, carbon dioxide gas, and water. Normally sodium bicarbonate is added until the fizzing ceases, at which point no more CO2(g) is produced.
