Group 12 element a substance into the molten form of the metal, or through the process of electroplating which may be passivated by the use of chromate salts. Group 12 elements are also used in electrochemistry as they may act as an alternative to the standard hydrogen electrode in addition to being a secondary reference electrode. In the US, zinc is used predominantly for galvanizing (55%) and for brass, bronze and other alloys (37%). The relative reactivity of zinc and its ability to attract oxidation to itself makes it an efficient sacrificial anode in cathodic protection (CP). For example, cathodic protection of a
