In separate experiments, 70.00 mL samples of 0.0100 mol L HNO₂(aq) and 0.0100 mol LHI are each titrated with 0.0200 mol L NaOH(aq) at 25 °C. For HNO2, pK₂=3.14 at 25 °C. Calculate the following for each titration and enter your answers in the boxes provided. (For you to think about: Which of the quantities are the same for the two titrations?) (a) Volume of NaOH required to reach the equivalence point (b) pH before any NaOH(aq) is added (c) pH at the half- neutralization point (d) pH at the equivalence point (e) pH after the addition of 50.00 mL of NaOH(aq) Titration of HNO2 VNaOH= Number pH = Number mL For part (a), enter volumes accurate to 2 decimal places. pH = Number pH = Number Titration of HI pH = = Number VNaOH = || Number For parts (b)-(e), enter pH values accurate to 2 decimal places. pH = Number pH = Number pH = Number mL pH = Number
