Electrolysis of aqueous solution Flashcards
1
Q
What are aqueous solutions dissolved in?
A
Aqueous solutions are dissolved in water
2
Q
How are hydrogen and hydroxide ions present during the electrolysis of an aqueous solution?
A
The water molecules ionise(split) forming hydrogen ions and hydroxide ions
3
Q
When is hydrogen produced at the cathode?
A
Hydrogen is produced at the cathode if the metal is more reactive than hydrogen
4
Q
Which metal is used as an inert electrode?
A
Platinum is often used as inert electrodes.
5
Q
What happens if the aqueous solution contains halide ions?
A
If the solution contains halide ions, then the halogen will be produced at the cathode
