- Statement I: Rusting of iron is a chemical process where iron reacts with oxygen and moisture (water) to form hydrated iron(III) oxide, commonly known as rust. This involves the formation of new substances with different chemical properties, characteristic of a chemical change. This statement is correct. - Statement II: Galvanisation is a process where a protective coating of zinc is applied to iron or steel. This zinc layer acts as a barrier and also provides cathodic protection, preventing the underlying iron from rusting. This statement is correct.
Given below are two statements : Statement I : Rusting of Iron is a chemical change. Statement II : The process of depositing a layer of Zinc on Iron is called galvanisation. In the light of the above statements, choose the most appropriate answer from the options given below :
