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-
What would the product/structure be if the reaction of methyl benzoate was a subsitution (add H and NO2 to it)?
Calculate how many mL of 0.100 M NaOH are needed to neutralize completely 49.0 mL of 0.0800 M H2SO4 (forming Na2SO4 and water).
Consult your lecture or lab text and give a complete structuer for the 'intermediate borate ester' formed in the reduction of 2-butanone with NaBH4. Why is it necessary to add water after the reaction is complete?
Calculate the cell potential at 298 K of the galvanic cell below. Assume no current draw and a perfect salt bridge. Pt(s)| Cu2+ (0.05 M), Cu+ (0.50) || Fe2+ (0.01 M), Fe3+ (0.10 M) | Pt(s)
