In a titration, the equivalence point is the moment at which the number of moles of H+ from the acid that has been added is equal to the number of moles of OH- from the base that has been added. Remember that in a molecule like H2SO4, there are 2 moles of H+ per mole of H2SO4.
18.63 mL of 0.100M H2SO4(aq) is placed in a beaker. After 16.42 mL of NaOH is added to the beaker, the equivalence point is reached. What is the concentration (M) of the NaOH solution?
