A cell consisting of a saturated calomel electrode as well, Ask an Expert

Academics

A cell consisting of a saturated calomel electrode as well as a lead ion-selective electrode developed a potential of -0.4812 V when immersed in 50.00mL of a sample. A 5.00-mL addition of standard 0.02500 M lead solution caused the potential to shift to -0.4390 V. Compute the concentration of lead in the sample in ppm.
