Interpretation:
The substances which act as reducing agent and oxidizing agent in the given
Concept Introduction:
Redox reactions:
It is a type of reaction in which both oxidation and reduction happens simultaneously. One get oxidized and one get reduced.
Example:
Oxidation of Zinc increased by two and Hydrogen reduced by one;
Oxidizing agent:
Oxidizing agent will gain electrons but itself will get reduced in the reaction. Oxygen, Hydrogen peroxide are good oxidizing agent.
Reducing agent:
A compound or an element donates electron in a redox reactions. Reducing agent will get oxidized in a reaction.
Lithium Aluminium Hydride and Sodium borohydride are good reducing agents.
(b)
Interpretation:
The substances which act as reducing agent and oxidizing agent in the given redox reaction has to be identified.
Concept Introduction:
Redox reactions:
Both reduction and oxidation will occur simultaneously in a redox reaction, one will get reduced and the other will get oxidized.
Example
Here Cu is reduced and
Oxidizing agent:
The substance which accepts electrons in a redox reaction is known as oxidizing agent.
Hydrogen peroxide, oxygen are examples of oxidizing agent.
