Factors Affecting Pdts Of Electrolysis

Question 1

What are the three factors?

Answer 1

1. E node value
2. Conc of ions
3. Nature of electrodes

Question 2

when concentrated solution is used, what happen if

1. E value very big
2. E value very small

Answer 2

1. Which one more positive
2. Shifting of equilibrium
   - LHS decreases E value

Question 3

How to determine if E is very big?

Answer 3

Use the pdt to explain

Question 4

Two types of ions that will never get discharged?

Answer 4

Large anions: NO3-, SO42-
-> break a lot of covalent bonds

Aq cations of highly reactive metals
-> high negative E value
