at equivalence point, Moles OH- added = moles H+ Molarity NaOH x vol. OH- x 1 OH- per NaOH = moles OH- = moles H+ = Molarity H2SO4 x vol H2SO4 x 2 H+ per H2SO4 More generally, M1V1E1 = M2V2E2, where E is the equivalence factor, number of H+ per formula unit for acids and number of OH- per unit for bases Solution at equivalence point, Moles OH- added = moles H+ Molarity NaOH x vol.
