A chemist needs a HCl solution with a molarity of less than 0.400 M for an experiment. To find out if a sample of HCl solution can be used in the lab, the chemist performs a titration to neutralize 59.2 mL of the HCl with 45 mL of 0.400 M NaOH. Based on the results, will the acid be useful for the chemistâ€™s experiment?

1. mLHCl x MHCl = mLNaOH x MNaOH
Substitute and solve for MHCl and compare with 0.400.
Of course you need not do a calculation. If the NaOH is 0.400 and it takes more HCl to neutralize the NaOH you know HCl is weaker than NaOH or HCl < 0.400M
