This is a draft cheat sheet. It is a work in progress and is not finished yet.
Electrolysis Basics
Electrolysis: Non-spontaneous reaction converting electrical energy into chemical |
| |
Electrode Charges |
Anode: Positive (+) |
Cathode: Negative (-) |
| |
Anode still oxidides |
Cathode still reduces |
Faraday's Law
1st Electrolysis Law |
Amount of substance made/used is directly proportional to electrical charge through cell |
| |
2nd Electrolysis Law |
To make 1 mole of a substance, electrons must be consumed (dependent on substance's charge) |
Electrolytes
Aqueous Solution |
Molten Electrolyte |
Assume H₂O is also present |
Pure substance |
H₂O may 'interfere' with reaction |
No H₂O present |
|
|
Electrochemical Series
Strongest oxidant at cathode reacts with strongest reductant at anode |
Unwanted reactions may occur if other substances are present |
| |
Shape |
'Z' - shaped on series |
Flatter 'Z' for stronger reaction |
Associated Formulas
Electrical Charge Formula |
Q = I x t |
| |
Mole No. Of Electrons Formula |
n(e⁻) = Q ÷ F |
| |
Mole Ratio |
Unknown ÷ Known |
| |
Molar Formula |
n = m ÷ Mᵣ |
