- Ag video: youtube.com/watch?v=npqooiE6DhEWhich 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 reductionsCalculate the amount of phycocyanin in Sample 1 in mg where A620=0.211 and A650=0.086, taking into account the dilution factor as per question 6 (100ul), and the total volume of extract as per question 4 (140ml) .
