In the second image it states that after I
pass the equivalence point, I should add 2ml of aliquots of NaOH
until there's no PH change. How do I identify when the equivalence
point is?

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...

a) Use this plot to estimate the volume of NaOH
required to reach the equivalence point of each titration
curve.
b) Estimate the original concentration of weak acid in
solution before strong base was added.
c) Find the midpoint pH for each of the trials using
half the volume of NaOH required to reach the equivalence point for
that trial. Check if this pH is at the most flat part of the
titration curve. This is the pKa of the...

1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...

If the pH at the equivalence point for titration of a monoprotic weak acid with NaOH is 9.00, and 10 mL of base is required to reach the equivalence point, how would you determine the pKa of the acid? the pKa is 9.00 determine the pH after 5 mL of base is added; this is the pKa determine the pH when 20 mL of base is added; this is the pKa the pKa is -log(9)
