Differences between oxidation and reduction in table form
Below is a table highlighting the key differences between oxidation and reduction:
| Aspect | Oxidation | Reduction |
|---|---|---|
| Electron Transfer | Involves the loss of electrons. | Involves the gain of electrons. |
| Oxidation State | Increases the oxidation state of an element. | Decreases the oxidation state of an element. |
| Example | Iron (Fe) oxidizes to form iron oxide (Fe2O3). | Copper (Cu2+) ions reduce to form copper (Cu). |
| Oxygen Gain/Loss | Involves the gain of oxygen atoms. | Does not necessarily involve oxygen gain/loss. |
| Hydrogen Gain/Loss | Involves the loss of hydrogen atoms. | Involves the gain of hydrogen atoms. |
| Chemical Process | Often associated with reactions with oxygen. | Can involve various elements and compounds. |
| Energy Change | Generally releases energy (exothermic). | Often requires energy (endothermic). |
| Reaction Participation | Oxidizing agents facilitate these reactions. | Reducing agents facilitate these reactions. |
| Electron Donor/Acceptor | Donates electrons to other substances. | Accepts electrons from other substances. |
| Electrochemical Cell | Oxidation occurs at the anode (+). | Reduction occurs at the cathode (-). |
| Corrosion | Often leads to the corrosion of metals. | Can help prevent the corrosion of metals. |
This table provides a concise overview of the main differences between oxidation and reduction, showcasing their contrasting characteristics and roles in chemical reactions.
