In a terrible accident, a solution consisting of 2.15 kg of nitric acid, HNO3, was spilled on the lab floor. Very quickly,
you decide to throw 2.00 kg of sodium carbonate, Na2 CO3 , on the spilled acid. You then run out of the building due to
the significant quantities of carbon dioxide that would form due to the reaction. As you stand outside, you wonder, "Did I
add enough sodium carbonate to neutralize the acid?".
a) Did you add enough sodium carbonate to neutralize the acid?
Yes
O No
b) In the event that you did not add enough sodium carbonate, how much extra would be needed to completely neutralize
the acid? If you have added enough, please enter a value of 0 (zero).
