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 of galvanized steel acts as one of these components to prevent corrosion. Ships (10[1])often use zinc as a “sacrificial” one (10[1])of these (10[1])components. One of these components continuously dissolves to provide (-5[1])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. For 10 points, name this electrode (10[1])often (-5[1])paired with a cathode. ■END■ (10[5])
