Strategies to solve questions related to redox reactions and oxidation states in the chemistry section of the JEE Advanced exam:

1. Understand the basics:
- Familiarize yourself with the concept of redox reactions and oxidation states.
- Understand the rules for assigning oxidation states to different elements in a compound.

2. Identify the reactants and products:
- Carefully read the question and identify the reactants and products involved in the redox reaction.
- Note down the chemical formulas of each species.

3. Assign oxidation states:
- Assign oxidation states to each element in the reactants and products.
- Use the rules for assigning oxidation states to determine the oxidation state of each element.

4. Determine the change in oxidation states:
- Compare the oxidation states of each element in the reactants and products.
- Identify the elements that have undergone a change in oxidation state.

5. Identify the oxidizing and reducing agents:
- The oxidizing agent is the species that causes oxidation by gaining electrons.
- The reducing agent is the species that causes reduction by losing electrons.
- Identify the oxidizing and reducing agents based on the change in oxidation states.

6. Balance the redox equation:
- Write the unbalanced redox equation using the chemical formulas of the reactants and products.
- Balance the equation by adding coefficients to balance the number of atoms on each side.
- Balance the electrons transferred by adding electrons as necessary.

7. Check the balanced equation:
- Verify that the number of atoms and charges are balanced on both sides of the equation.
- Check if the oxidation states of the elements match the assigned oxidation states.

8. Solve the question:
- Use the balanced equation to answer the specific question asked in the JEE Advanced exam.
- Calculate the number of moles, mass, or other quantities as required.

9. Practice and review:
- Solve practice questions related to redox reactions and oxidation states to improve your understanding and speed.
- Review the concepts and strategies regularly to reinforce your knowledge.

Remember to manage your time effectively during the exam and practice solving different types of redox reactions and oxidation state questions to improve your problem-solving skills.
