1.	`Zn` acts as sacrifical or cathodic protect iont to prevent rusting of iron becauseA. `E_(OP)^(@)` of `Zn lt E_(OP)^(@)` of FeB. `E_(OP)^(@) ` of ` Zn gt E_(OP)^(@)` of FeC. `E_(OP)^(@) ` of `Z n =E_(OP)^(@)` of FeD. Zn is cheaper than iron
Answer» Correct Answer - B Zn is oxidised in place of iron and iron acts as cathode if Zn plating or galvanisation of iron is made and thus called cathodic protection . Since Zn is oxidised and thus also called sacrifical protection .
