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 and the acid, and the pKa of the acid.
The pH is 1.
The pH is calculated by determining the concentration of weak acid present in the solution, using an ICE table to calculate the proton concentration present after hydrolysis, and taking the negative log of the result.
The pH is based on the concentration of protons present in the solution, which is equal to the original concentration of the acid. The pH is calculated by determining the concentration of weak conjugate base present in the solution, using an ICE table to calculate the hydroxide ion concentration present after hydrolysis, subtracting pOH from 14, and taking the negative log of the result.

curve. Prior to the titration, the pH is determined by the
