The EPA is collecting water samples from the Allegheny River and testing for lead ion concentrations. They are measuring concentrations using an lead ion selective electrode. Al (s) | Al* (1.4 x 10) || Pb²* (?)| Pb (s). When they put the electrode in the water solution they measure a value of 1.45 V. Write a balanced redox reaction. What is [Pb2*] in the water sample? The EPA limit for drinkable water is 0.06 mg/L. Is the water drinkable?
