The anodic stripping voltammogram for Fe(III) in seawater is shown in A below. Then, the anodic stripping voltammograms obtained after successive standard addition of 4 ppb Fe(III) are shown in B and C. Find the concentration of Fe(III) in the seawater sample.

Map . Current Cathodic potential Time Potential (V) During a cyclic voltammetry experiment, a triangular waveform is applied to the Select answer electrode. As the potential is swept more negatively, a Select answer wave is exhibited, during which time analyte is Select answer 0. The potential is reversed once the switching potential is reached. Once the potential is reversed, the Select answer wave is exhibited as analyte is Select answer

van der Berg and Huang have reported a method for the determination of the concentration of vanadium (V) in sea water by adsorptive stripping voltammetry after forming a complex with catechol. The Vanadium-catechol complex is deposited on a hanging mercury drop electrode at a potential of -0.1 V versus a Ag/AgCl reference electrode. A cathodic potential scan gives a stripping peak that is proportional to the concentration of V. The following standard additions were used to analyze a sample of...
