Question

How much 0.10 M Base (in mL) is required to neutralize 8.00 mL of the 0.10 M acid?
Base Acid Base Volume (mL)
NaOH HCl
NaOH HC2H3O2

Answer 1

You need to know if the acid/base is 1:1 or not. If 1:1 you may use a simple
mL x M = mL x M

If not 1:1 you must go through moles and coefficients.

Answer 2

Both answers are 8. I don't know why or how, though.
