CBSE Class 11-science Chemistry Redox Reactions
Oxidation and reduction always occur simultaneously, thus the name REDOX reaction.
Elements which lose electrons are reducing agents and those which gain electrons are oxidising agents.
Oxidation is the increase in oxidation number and reduction is the decrease in oxidation number of an element in the given substance.
Balancing Redox Reactions
To balance a redox the mass and charge both are balanced. The principle used in balancing redox reaction is that number of electrons lost is same as number of electrons gained.
Redox reactions are balanced by oxidation number and Half-reaction method.
