QUESTION 1 · 1 POINT *This is a part of the 6 part titration practice problem. The titration set up is as follows: 35.0 mL of 0.125 M HCN is titrated with 0.200 M KOH. The pka of HCN is 9.21. What is the pH once half of the equivalence volume has been added? Select the correct answer below: 11.34 9.21 O 7.00 10.22...
1.Draw the pH titration curve for the titration of 35 mL of 0.150 M acetic acid with 0.200 M NaOH. Include the pH values and NaOH volume requested below on your pH titration curve. Also, put on the curve the species that dictates the pH at the requested pH values. For acetic acid, K = 1.8 x 10%. 1) the initial pH 2) the pH after 15.0 mL of NaOH have been added 3) the volume of NaOH at the...
