A constant that includes pi and the density of this element is multiplied by the concentration of the depolarizer in the Ilkovic (“eel-koh-VITCH”) equation. This is the lighter of two elements that classically acts as the working electrode in anodic (“uh-NOH-dic”) stripping voltammetry. This element’s large voltage window makes it useful in devices that dispense this element through a capillary. (15[1])An apparatus with a cathode of this (*) metal and a graphite anode is used to electrolyze alkali chloride solutions via the Castner-Kellner process. (10[1])While it has largely been (-5[1])phased out (-5[1])in favor of an analogous silver-based device, a “saturated” (10[1])reference electrode common in voltammetry experiments is based on a reaction between this element and its chloride, calomel. Polarography experiments typically center on devices made from, for 10 points, what toxic metal that is a liquid (10[1])at (10[1])room temperature? ■END■ (10[1])
