Which are true for polarography? Polarography is amperometry conducted with a dropping Hg electrode. The diffusion current in the plateau region of the polarographic wave is proportional to the concentration of the analyte and is used for quantitative analysis. The half-wave potential for maximum current is characteristic of a given analyte in a given medium and can be used for qualitative analysis for the analyte. III IV Fresh Hg drops give reproducible results. V Polarography is used to primarily to study oxidations Hg may reduce when studying reductions. O II, IV, and V O II, III, and V O II, III, and IV O I and V I, III, and IV
