Class 11 oxidation- In chemistry, oxidation is a process that involves the loss of electrons by a substance. It is often associated with an increase in the oxidation state of an atom, ion, or molecule. Oxidation reactions are fundamental in various chemical and biological processes. Here’s a brief overview of oxidation concepts typically covered in Class 11 chemistry:
- Oxidation and Reduction:
- Oxidation: The process in which a substance loses electrons.

- In compounds, hydrogen is usually assigned an oxidation number of +1, and oxygen is usually assigned an oxidation number of -2.
- Balancing Redox Reactions:
- Oxidation numbers are used to balance redox reactions.
- The number of electrons lost in oxidation must equal the number gained in reduction.
- Half-Reactions:
- In a redox reaction, the oxidation and reduction processes can be separated into two half-reactions.
- Each half-reaction shows the change in oxidation state for a particular species.
- Activity Series:
- The activity series is a list of metals arranged in decreasing order of their chemical activity.
- It helps predict whether a metal will undergo oxidation in a given reaction.
- Corrosion:
- Corrosion is a type of oxidation reaction that occurs with metals, resulting in the deterioration of metal surfaces.
- Oxidizing and Reducing Agents:
- An oxidizing agent causes oxidation in another substance by accepting electrons.
