Hydrazine and hydroxylamine are depolarizers used to avoid codeposition on these objects. For 10 points each:
[10m] Name these objects that control the scan rate in techniques like CV. An auxiliary, reference, and working one of these objects are arranged into a namesake three-component system in techniques like stripping analysis.
ANSWER: electrodes [accept anodes or cathodes; accept auxiliary electrodes or reference electrodes or working electrodes; accept three-electrode cell or three-electrode system; accept anodic stripping voltammetry or cathodic stripping voltammetry]
[10h] This technique is characterized by its use of dropping or static mercury drop electrodes. Like hydrodynamic voltammetry, the working electrode performs a linear scan in this technique.
ANSWER: polarography
[10e] Polarography is often used to determine this quantity for samples, which lends its name to galvanic cells with identical electrodes and electrolytes. This quantity is measured in units of moles per liter, or molarity.
ANSWER: concentration [accept concentration cells]
