Which is correct for polarography? I-polarography is an amperometry method conducted with a dripping Hg electrode. II-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. III-The half-wave potential is characteristic of the analyte in a given environment and can be used for qualitative analysis. IV-fresh Hg drops provide reproducible results. V-polarography is primarily used to study oxidations, Hg can be reduced when studying reductions
