An electrochemical series is:
|
A list of different electrode potential (half cells), all relative to the standard hydrogen electrode.
|
|
|
Electrode potential (half cells):
1) Are written as? 2) The reactant is? The product is? |
1) Written as reductions.
2) The Oxidising Agent. 3) The reducing agent. |
|
|
The strongest:
1) Oxidising agent? 2) Reducing agent? |
1) The most +ve.
2) The most –ve. |
|
|
To calculate the Ecell:
|
Eright – Eleft.
- The left is the reducing agent (most negative). - The right is the oxidising agent (most positive). |
|
|
If the overall e.m.f. (Ecell) is +ve:
|
Then the reaction is spontaneous in the forwards reaction (It can happen).
