pH, Acid, Base, Salt and Buffers Post-Lab (Part 1) 1. A student performing the first part of this lab, measures a pH of 2.05 for a hydrochloric acid solution that should have a pH of 2.50. Assuming the pH meter is properly calibrated, what does this. result indicate about the sample of HCI that was prepared? Name: solution ont properl y diluted 2. Use the literature value of K, for acetic acid to calculate the percent ionization of a 0.40M solution. Explain why solutions of HCI and of HC.H,O, at identical concentrations have different pH value Assume the meter used to measure pH is properly calibrated and show all acid dissociation quations and equilibrium expressions to support your explanation.) 3. Gonsider how the concept o nt
