If it takes 54 mL of 0.100 M NaOH to neutralize 125 mL of an HCl solution, what is the concentration of the HCl?
The first step would be to find the molar ratio in the reaction. Now generally, one can simplify strong acid-strong base reaction by saying:
Acid+Base ->Salt+ Water
So our acid and base are in a 1:1 molar ratio in this case- so an equal amount of
Using the concentration formula:
We were given concentration and volume of
Hence, this must be the number of moles of
