Interpretation:
The reason for the oxidation number of sodium to be same in given reaction needs to be explained.
Concept introduction:
Given reaction is
In a redox reaction the ions which are oxidized and reduced are called species and the ions which don’t take part in reaction is spectator ion.
Answer to Problem 8STP
