2. From your graph, determine the volume of sodium hydroxide needed to reach the equivalence point in the titration. 3. Calculate the volume needed to reach the half-equivalence point in the titration. 4. Find this half-equivalence point on the graph and determine its corresponding pH. 5. Use the half-equivalence point pH value to find the experimental pKa. To solve, recall that: pH = pK_a + log [base] / [acid]

When it is desired to characterize an acid, a potentiometric titration is used, and a graph of pH vs. Strong base volume. How can the value of pKa be obtained from this graph?

Draw the titration curve for the neutralization of 25 mL of HNO2 0.25 M with NaOH 0.15 M. Make sure to use at least 8 data points, including the initial pH, at least one point in the buffer region, the point where pH = pKa, the equivalence point, and at least one point after the equivalence point. Please provide a graph and show the math for the points. Thank you!

The graphs labeled (a) and (b) show the titration curves for two equal-volume samples of monoprotic acids, one weak and one strong. Both titrations were carried out with the same concentration of strong base.$$ \begin{array}{l}{\text { (i) What is the approximate pH at the equivalence point of }} \\ {\text { each curve? }} \\ {\text { (ii) Which graph corresponds to the titration of the }} \\ {\text { strong acid and which one to the titration of the weak }} \\ {\text { acid? }}\end{array}$$
