CHM 1046 - CHAPTER 16 & 17 INSTRUCTOR: DR MUSA, M.A 1. Calculate the percentage ionization of 0.0075 M butanoic acid (Ka = 1.5 x10 -5 ) 2. Phenolphthalein may be used as an indicator for the titration of: 3. In a solution prepared by mixing equal volumes of 0.20 M acetic acid and 0.20 M hydrobromic acid, the common ion is: 4. Determine the pH of the following solution. Initial concentrations are given. [HC 2 H 3 O 2 ] = 0.250 M, [HCl] = 0.120 M [K a = 1.8 x 10 -5 ] 5. Calculate [Cr 3+ ] in equilibrium wit Cr(OH) 4 - when 0.010mol of Cr(NO 3 ) 3 is dissolved in a liter of solution buffered at pH 10.0. 6. Determine the [F - ] of the following solution. Initial concentrations are given. [HF] = 1,296 M, [NaF] = 1.045 M, Ka for HF is 6.6 x 10

    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.
