Question ID: 782184
How many grams of NaHCO3 (battery acid) would you need to neutralize
500ml of battery acid (H2S04) that has been spilled on your garrage
floor?
Assume that the concentration of the battery acid is 12molL-1
The balance equation is:
H2SO4 + 2NaHCO3-----Na2SO4 +2CO2+ 2H20

You need to do the following 3 steps:

1. From the volume and concentration, figure out how many moles of H2SO4 there are.

2. From the balanced equation, you know that you need twice as many
moles of NaHCO3 to complete the reaction.

3. From the number of moles of NaHCO3 you got in (2), and also from
it's molecular weight in grams-per-mole, figure out how many grams are
needed.
