Buffer Net ionic reactions

A solution is prepared by mixing equal volumes of 0.20 M HC₂H₃O₂ and 0.40 M NaC₂H₃O₂

If 10.0 mL of 0.20 M HCl is added

Which equation is the correct net ionic reaction and the resulting change in pH?

• HCl + NaOH -> H₂O + NaCl

  pH decreases slightly

• H₃O⁺ + OH^- -> H₂O

  pH increases slightly

• H₃O⁺+ C₂H₃O₂^- -> H₂O + HC₂H₃O₂
