Electrochemical series and reaction spontaneity (Higher reduction potential species oxidises the one below; positive E°cell ⇒ spontaneous)
jee-mainjee-advancedneet-ug
Higher reduction potential species oxidises the one below; positive E°cell ⇒ spontaneous cell
What each symbol means
| Symbol | What it stands for |
|---|---|
| E^\circ | Standard reduction potential (SHE scale) |
When to use this
Standard conditions; compare reductions — stronger oxidising agent has higher E°.
