4) Suppose 50 mL of 0.1 M NaOH is added to 50 mL of 0.1 M HC2H302 (Ka = 1.8 X 10-5). This is a titration at its equivalence point. Calculate the pH of the resulting mixture.

In the titration of 25.0 mL of 0.1 M CH3COOH with 0.1 M NaOH, how is the pH calculated before the titrant is added? The pH is calculated by determining the concentration of excess hydroxide ions in the solution, subtracting pOH from 14, and taking the negative log of the result. The pH is 14. The pH is 7. The pH is calculated using the H-H equation for a buffer solution, using the ratio of the concentrations of the base...
