Quick explanation
Assign oxidation states using standard rules
- This point belongs to Oxidation, reduction and redox equations, especially Oxidation states.
- You need to be able to assign oxidation states using standard rules.
- The key ideas to know are oxidation and oxidation state.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Oxidation states to exam-style questions, flashcards, and revision notes for Oxidation, reduction and redox equations.
Quick student answer
What is the oxidation state of sulfur in H2SO4?
Direct answer
The oxidation state of sulfur in H2SO4 is +6.
Key terms
- Oxidation: The process of losing electrons or increasing oxidation state.
- Reduction: The process of gaining electrons or decreasing oxidation state.
Common trap
Incorrect assignment of oxidation states: Review the standard rules for oxidation states, especially for transition metals and their variable oxidation states.
