A) Using Linear Combinations of Atomic Orbital-Molecular Orbital Theory, draw the molecular orbital splitting diagram for CN- starting with the atomic orbitals that contain the valence electrons for each atom. Then fill the resulting molecular orbitals in the splitting diagram with the appropriate number of valence electrons.
B) Calculate the bond order for CN-
A solution is initially 0.050M in acetate, CH3COO- (Kb = 5.6 x 10^-10). 10.0mL of 0.10 M HCl is added. The Ka for the conjugate weak acid of CH3CHOO- is 1.8 x 10^-5. Calculate the pH for this solution at equilibrium.
