2. Find the equilibrium constant for the following chemical reaction:
CdCO3(s) + H20 → Cd2+ + CO2(g) + 20H
The constituent equilibria are:
→ Cd2+ + CO32-
→ CO3? + H*
H2CO3 → HCO3 + H+
H2CO3 → C2 (g) + H20
CdCO3(s)
HCO3
pK1 = 11.66
pK2 = 10.3
pk3 = 6.3
pK4 = -1.5
Note that you may also use the equilibrium expression for water.
