Pretaining to a question I asked earlier...?

Question

I asked the products from a Sulfuric Acid + Sodium Bicarbonate reaction, and from that was able to obtain the rest of the stoiciometry of the problem, but near the end, was a question pertaining to how it would react in a different situation.

If I spilled Sulfuric acid on a labratory floor, and tried to neutrilze the spill with baking soda, would it take more or less baking soda to neutralize the spill, if it had been made on bare concrete?
Thanks in advance!

Answer 1

In theory it would take less NaHCO3, because the H2SO4 would also react with the concrete.
