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?...
