used, marked pH changes can occur at the electrode surface as the reaction proceeds. 6. Stripping methods are more sensitive because the analyte is first preconcentrated by
electrochemical deposition at the electrode before the electrochemical analysis. All the
analyte that has been deposited can then be rapidly oxidized or reduced, producing a large
current. Homework Solutions for Chem 422
7. The purpose of the electrodeposition step in stripping analysis is to concentrate the analyte
on the surface of the working electrode. 8. Mercury film electrode vs. Pt or carbon microele...
