Question
Calculate the pH at the halfway point and at the equivalence point for each of the following titrations. a. 100.0 mL of 0.20 M HC7H₂O₂ (K₂ = 6.4 × 1 : 10-5) titrated by 0.10 M NaOH pH at the halfway point = pH at the equivalence point = b. 100.0 mL of 0.60 M C₂H5NH₂ (K₁ = 5.6 × 10- pH at the halfway point = pH at the equivalence point = c. 100.0 mL of 0.40 M HCl titrated by 0.15 M NaOH pH at the halfway point = pH at the equivalence point = titrated by 0.60 M HNO3
