For 10 points, name these devices at which oxidation and reduction occur, termed anodes when they gain electrons and cathodes when they lose electrons.
Selectivity coefficients for these devices give their relative responsivity to different analyte ions. Ion-selective ones can have crystalline or noncrystalline membranes, and glass pH meters possess a silver and silver chloride reference device of this type. (*) Reduction potentials are typically given with respect to the standard hydrogen type of this device, and other standards include the calomel type of this device.
