The following question is a sub-question derived from this simulated incident:  A student accidentally spills a 1.00 L bottle of concentrated (100%, not aqueous) 18.0 M sulfuric acid on the floor of the laboratory.  She attempts to neutralize the spill by pouring a 5.00 kg box of baking soda (sodium hydrogen carbonate - NaHCO3) onto the acid. 

question:  Would a floor consisting of bare concrete require more, less, or the same amount of baking soda to neutralize the spill.  Explain. 

Seeing as this is just a problem which I have no idea how to answer, or ever where to start, I cannot actual show that I have attempted the problem, but trust me, a good amount of time has been spent investigating and brainstorming ideas, but without success. 

Any help, even a hint, is greatly appreciated.

You were not given any information about the original floor. Thus you are asked to compare apple with youcantbeevensureitsfruit. IMHO no way to precisely answer the question.

I suppose that the idea was that you have to take a look at concrete composition and check if its components will in any way react with sulfuric acid (neutralizing it for example) - or it is an open question which is targeted at checking your ability to think (thus no one good answer).
