(a)
Interpretation:
The half reaction that takes place to tin plate on an iron can needs to be determined.
Concept Introduction:
A
In such types of reactions, one of reactant is oxidized and other is reduced. A species undergo oxidation if it gains oxygen or lose hydrogen atoms. On oxidation, the oxidation number of the species increases, and loss of electrons takes place. Opposite to this, in reduction it gains hydrogen or lose oxygen atoms and the oxidation number of the species decreases due to gain of electrons.
(b)
Interpretation:
The reason for iron can to act as cathode needs to be explained.
Concept Introduction:
A redox reaction is a reaction in which oxidation and reduction both processes takes place simultaneously.
In such types of reactions, one of reactant is oxidized and other is reduced. A species undergo oxidation if it gains oxygen or lose hydrogen atoms. On oxidation, the oxidation number of the species increases, and loss of electrons takes place. Opposite to this, in reduction it gains hydrogen or lose oxygen atoms and the oxidation number of the species decreases due to gain of electrons.
(c)
