Question

1))))Weak Base Titration: At the Equivalence Point a))A 11.30 mL solution of 2.47 M pyridine (C5H5N, a weak base) is titrated to the equivalence point with 22.4 mL of HNO3. What is the pH at the equivalence point? Kb for pyridine is 1.7 X 10-9. b))))Click on all of the dominant species that you would expect to find in solution at the equivalence point. Do not include H3O+ and OH-ions unless they are coming from another source other than the autoionization of water. NO3- ,C5H5N, OH- ,H3O+ ,C5H5NH+, HNO3 *********************************************** 2))))Q2:Often the pH of the solution can affect the solubility of metal hydroxide salts as a result of the common ion effect. The Ksp for Cd(OH)2= 7.20 X 10-15. What is the molar solubility of Cd(OH)2 in a solution with a pH of 8.90?
