Need to create pH vs. volume graph and fill out table from experimental data below. I have posted the pH vs. volume graph I have created, not sure if it is right, need to help finding stoichiometric point. I am also required to fill out the table posted below. MY LAB GROUP BAILED ON ME PLZ HELP!!!!!!!!!!!!!!!!!!!!!!!!!
My calculations so far... really need help...
5) 71.0 - 0.0 = 71.0
6) ---- graph already made if correct -----
7) 0.1 M (71 mL) = 0.1M (0.071 L) = 0.0071 mol = 7.1*10^3 moles
8 - 13) ??????????????

can someone help me answer these 5 questions and figire this graph out please? 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...
