Electrolysis Flashcards
1
Q
Positive ions
A
Cations move towards the cathode and are reduced
2
Q
anions
A
Move towards the anode and are oxidised
3
Q
Reactivity series
A
Potassium Sodium Calcium Magnesium Aluminium Carbon Zinc Iron Tin Lead Hydrogen Copper Silver Gold Platinum
4
Q
Molten compounds
A
Normal stuff is produced
5
Q
Aqueous solution
A
Cathode: If the metal is above hydrogen in reactivity series, hydrogen will be produced – bubbling will be seen at the cathode
Anode: either oxygen will be given off or a halide will
