Consider the titration of a 21.0-mL sample of 0.100 M HC₂H3O3 (K, 1.8 x 10-5) with 0.130 M NaOH. Part A Determine the initial pH. Express your answer to two decimal places. pH = 2.87 Submi, Previous Answers ✓ Correct Correct answer is shown. Your answer 2.85 was either rounded differently or used a different number of significant figures than required for this part. Begin by calculating the equilibrium concentration of H₂O. HC₂H₂O₂ is a weak acid that dissociates partially. Prepare an ICE table showing the equilibrium concentrations of the species in the solution. Assume that z mol HC₂H5O₂ per liter dissociated. Your table should look like this: HC_H:O, C_HO | H_O*] 0.100 0 20 +2 Initial Change Equilibrium 0.100- +2 2
