Identify redox reactions by tracking oxidation numbers and electron transfer, distinguishing oxidation and reduction, and recognizing when electrons are gained or lost in a reaction.
Master oxidation numbers using the rules for hydrogen, oxygen, and group elements. Explore how neutral compounds sum to zero and polyatomic ions carry a charge.
Learn the difference between oxidation numbers and oxidation states, including how to assign integers and fractional averages using electronegativity, with examples like sulfuric acid and carbon compounds.
Learn to balance redox reactions in acidic medium using the half-reaction method: identify oxidation numbers, separate half-reactions, balance charge, oxygen, and hydrogen with water and H+, then balance electrons.
Learn to calculate n factor values for intramolecular and intermolecular redox reactions by balancing oxidation numbers, tracking electron transfer, and determining oxidation and reduction partners.
At the end of the course, the students will be able to learn complete details about redox reactions.
The course includes:
Redox reactions: It is a reaction in which both oxidation and reduction reaction take place simultaneously.
Types of redox reaction: There are four types of redox reactions: Intermolecular redox, intramolecular redox, disproportionate redox and co-proportionation redox reaction.
Intermolecular redox reaction: The redox in which one reactant undergoes oxidation and another reactant undergoes reduction reaction.
Intramolecular redox reaction: The redox in which in a given reactant, one element undergoes oxidation and another element undergoes reduction.
Disproportionate redox reaction: The redox in which in a given reactant, same element undergoes both oxidation and reduction reaction.
Co-proportionation redox reaction: It is reverse of disproportionate redox reaction.
How to identify oxidation and reduction reactions: increase in oxidation number is oxidation and decrease in oxidation number is reduction.
How to calculate oxidation number
Oxidation rules: It helps to determine the oxidation number of an element in any molecule, compounds, polyatomic ions and complex compounds.
Application of oxidation rules: These rules help to identify strength of acids and bases, identifying oxidizing agents and reducing agents.
