June 2017 NY Regents Chemistry Exam


40 Which statement explains why 10.0 mL of a 0.50 M H2SO4(aq) solution exactly neutralizes 5.0 mL of a 2.0 M NaOH(aq) solution?

(1) The moles of H+(aq) equal the moles of OH-(aq).

(2) The moles of H2SO4(aq) equal the moles of NaOH(aq).

(3) The moles of H2SO4(aq) are greater than the moles of NaOH(aq).

(4) The moles of H+(aq) are greater than the moles of OH-(aq).


Solution: In a neutralization reaction, the moles of H+(aq) equal to the moles of OH-(aq) at the equivalence point.
