Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...

pH at equivalence is 8.40
It's a tritration with a breaker filled with 0.1894 M CH3COOH and a buret with 0.2006 M NaOH. | added 9.44 mL of NaOH to the CH3COOH to find the equivalence point. Find the Ka of CH3COOH 9. Use your data to estimate Ka of the weak acid. Show all working (give your answer to thee sig figs) Hint: Estimation of K The pH at the equivalence point can be used to estimate the K....
