Unformatted text preview: NH 3 NO 3 K b (CH 3 NH 2 = 4.4 * 10 −6 ) Test 3 Practice 10. Classify the salt CH 3 NH 3 NO 2 as acidic, basic or neutral (see question above and K a (HNO 2 ) = 7.1 * 10 −4 ) 11. Given that 25.0 g of Zn(IO 3 ) 2 (K sp = 3.9 *10 −6 ) are thrown into 3.00 L of water, solve for the concentration of Zn 2+ and IO 3 − . 12. Given a 1.00 L solution that is 0.100 M ZnNO 3 and 135 g of Zn(IO 3 ) 2 are added to the solution, what would be the concentration of Zn 2+ and IO 3 − . (Use K sp from previous question) 13. For a 1.00 L solution of 0.0250 M PbI 2 (K sp = 7.9 * 10 −9 ), would a precipitate be expected?...

    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.
