10. Each electroanalytical method (such as potentiometry, coulometry, and voltammetry) is by itself a group of techniques available from changes in experimental configuration and/or component. For example, there are two basic categories of coulometric techniques: potentiostatic coulometry and coulometric titration. (a) Select two out of the three electrochemical methods (i.e., potentiometry, coulometry, and voltammetry) mentioned above and name one technique for each of the two. (b) For each technique you named in (a), sketch (with       proper labeling       of each component - Pay attention to the fact that a component may have different names in different electroanalytical methods) the related experimental setup and describe (i) the electrical observables measured, (ii) the preferred experimental condition, and (iii) the operation/working principle, and then draw a representative plot (with proper labeling) produced from analyzing a chemical species of your interest using the named technique.
