1. Lead forms a relatively string complex with Acetate (CH3COO‑), according to the reaction: Pb(CH3COO)2(aq) = Pb2+ + 2 CH3COO- Log K for this reaction 1t 25 C is -3.4011. Determine the fraction of Lead that exists between Pb2+ and Pb(CH3COO)2(aq) if a soil fluid containing 10 ppb Pb2+ was in equilibrium with Acetate at [0.001) (for this, assume Pb2+ g =1)
