Tossup

In a process named for these components, a desmut (“de-smut”) solution is used to clean a surface before it is passivated with a thick, porous oxide layer that allows for easy dye application. The [emphasize] coating (-5[1])of galvanized steel acts as one of these components to prevent corrosion. Ships often use zinc as a “sacrificial” one (10[1])of these components. (10[3])One of these components (10[1])continuously dissolves to provide the coating material in electroplating. Metals that have a lower reduction potential will tend to act as one of these components, (-5[1])which electrons flow away from in a galvanic cell. (10[1])For 10 points, name this electrode (-5[1])often paired with a cathode. ■END■ (10[5])

ANSWER: anodes [accept sacrificial anodes; accept anodization; prompt on electrodes until read]
