Weak-Acid Strong-Base Titrations. These next questions relate to a 25 mL aliquot of 0.35 M acetic acid (Ka = 1.77 x 10) that is titrated with 0.20 M potassium hydroxide (KOH). (f) What is the pH of the acetic acid solution before the titration begins? (g) What is the pH after 14 mL of 0.20 M KOH has been added to the solution? Use the Henderson-Hasselbalch equation. (h) What is the pH at the equivalence point?
I need help with questions 1,3,4,5

Which of the following would make buffer system? A. a weak asid and NaCl B. a weak acident's conjugate base C. a strong acid and a weak acid D. alveak acid and a strong acid E....
1. Answer the following questions in detail. a) Given 25mL of 0.10 M HCl and 25 mL of 0.10 M acetic acid, will the amount of 0.10 M NaOH required to reach the equivalence point for each solution be the same, more, or less? b) Again, using 0.10 M NaOH, will the pH at the equivalence point of 25 mL 0.10 M HCl be the same, more, or less as the pH at the equivalence points for 25 mL of...

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...
i want answer to all questions please
