Chemical Reactions and Equations Mind Map
Use this learning tree to open the right concept in the right order. Start with a branch, expand it, then move into the concept page you need next.
Oxidation
highOxidation is a change in which a substance gains oxygen, loses hydrogen, or loses electrons.
In an exam answer, mention both the oxygen-based idea and the electron-based idea when possible.
Reduction
highReduction is a change in which a substance loses oxygen, gains hydrogen, or gains electrons.
If oxygen is removed from a compound, write reduction confidently and then support it with the reason.
Redox Reaction
mediumA redox reaction is a reaction in which oxidation and reduction happen at the same time.
If one substance is oxidized, check which other substance is reduced in the same reaction.
