QUESTION 10 Ionic Equilibria, pH, Indicators, & Buffers In Part C of this lab, the pH values of dilute solutions of acetic acid (HC2H302) of various concentrations are measured using a pH meter. These pH values are then used to calculate the equilibrium constant, K, for each solution. If the given concentration of an acetic acid solution is 0.010 M, and the pH is measured to be 3.35, what is the value of the equilibrium constant, K?

In this lab, we will experimentally determine the titration curve for the titration of a weak acid solution against a strong base solution. The weak acid we will use is potassium hydrogen phthalate, KHP, its chemical structure is shown below. KHP is an ionic compound composed of a potassium cation K+ and a hydrogen phthalate anion HP–. HP– is a weak acid and upon dissolving in water, can lower the pH of the solution. (a) Suggest the chemical reaction(s) when a solid sample of KHP is dissolved in water, writing out the chemical equations for them. (b) Sketch the structure of KHP from above and circle the hydrogen atom that is responsible for its acidity. (c) Calculate the pH of a solution made of 0.50 g of KHP and 50 mL of water. KHP has a molar mass of 204.2 g and at 25 °C has a pKa of 5.4.

Question Completion Status: QUESTION 28 Check all that is true for a buffer solution. The pH of a buffer solution can be determined by the Henderson-Hasselbalch equation When the acid and base components of the buffer solution is present in equal amount, pH = pKa When a strong acid is added to a buffer solution, the acid component of the buffer solution will decrease in concentration. A buffer solution is resistant to changes in its pH A buffer solution contains a weak(<100% ionization) conjugate acid/base pair QUESTION 29 Which of the following cannot be a buffer solution? Each component is at 0.050 M concentration. OHCI/CI OH-C₂H302/ C2H30₂ O NH4+/NH3 O HNO₂/NO₂ QUESTION 30 Below is a titration curve of a sample of monoprotic acid (HA) by NaOH.
