17. Acid and Base Equilibrium
Ka and Kb
4PRACTICE PROBLEM
In aqueous solutions, the acidities of methanol and water are almost identical and are increased when coordinated with a central metal cation. The resulting metal complex then acts as an acid and donates a hydrogen ion to a base. Shown below is M(CH3OH)6n+ (n = 1, 2, or 3), a metal cation with methanol ligands attached to it.

What happens to the equilibrium constant (increases, decreases, or remains the same) as the value of n increases? Explain.
