Ignoring activities, determine the molar solubility of copper (I) azide (CuN3) in a solution with a pH of 13.11. Ksp (CuN3) = 4.9 × 10-9; Ka (HN3) = 2.2 × 10-5.
Use the systematic treatment of equilibrium to solve this problem.Pertinent Reactions are:CuN3(s) <==> Cu+ + N3-N3- + H2O <==> HN3 + OH-H2O <==> H+ + OH-
