1.) Answer the following questions: Why do coulometric methods do not require preliminary calibration against standards? A. The relationship between the quantity measured and the analyte concentration is often not linear. B. The relationship between the quantity measured and the analyte concentration can be derived from theory and atomic mass data. C. Both A and B D. Neither A nor B The advantage of performing voltammetry with ultramicroelectrodes is A. their low IR loss which permits their use in low-dielectric-constant solvents such as hydrocarbons. B. their small size which permits electrochemical studies on exceedingly small samples such as the inside of living organs. C. their great speed of equilibration even in unstirred solution. D. All of A, B, and C Which is not a characteristic of a reference electrode? A. It must have a known potential. B. It must have a constant potential. C. Its potential must be dependent on the composition of the solution. D. It is employed in conjunction with the indicator electrode. .A in polarography is a nonfaradaic charging current that arises from the flow of electrons required to charge individual drops of mercury as they form and fall. A is a constant faradaic current that is limited in magnitude by the rate at which a reactant is brought to the surface of a microelectrode. A. turbulent flow current, limiting current B. residual current, limiting current C. half-wave current, turbulent flow current D. residual current, half-wave current
