Practice Problems 1. Sketch a rough plot of pH versus volume of base added for the titration of 30mL of 0.500 M HI with 0.300M NaOH. a. What is the pH before any NaOH is added? b. What is the pH after 30mL of the NaOH is added? c. What is the volume of base in mL needed to reach the equivalence point? What is the pH here? d. What is the pH after 107% of the required base is added? 2. Dissolve 0.366g of CH 3 CO 2 H in enough water to make 100mL of solution. Then titrate the solution with a 0.299M solution of NaOH. K a of the solution is 1.8×10 -5 (only 3 sig. figs) a. What is the pH before any NaOH is added? b. What is the pH after 10.2 mL of NaOH is added? c. What is the pH after 14.25mL NaOH is added? d. What is pH after 20.4 mL NaOH added? e. What is pH after 25mL NaOH added? 3. What is the solubility (in mol/L) of BaSO 4 in the presence of 0.010M Ba(NO 3 ) 2 . K sp for BaSO 4 is 1.1×10 -10 . 4. Decide if each of the following is water-soluble. If it is, then tell what ions are made.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
