Production of chemicals by electrolysis

Question 1

Faraday’s laws

What is it used for

Answer 1

To find out how much metal is deposited on the cathode when you electrolyse an solution for a specific period of time using a known current.

Question 2

Faraday’s law

What is Faraday’s constant

Answer 2

1 mole of electrons have a total charge of 96,500 coulombs of charge.

Question 3

Faraday’s law

Equations Q=lt and Q=n(e)xF

Answer 3

Q= amount of charge in coulombs (C)
l= amps
t= time (seconds)
n(e)= amount of electrons (mole)
F=96500

Question 4

Electrolysis

Difference in electrolysis cells
-
-
-
-

Answer 4

• Forces are non-spontaneous
• Requires energy input
• Electron flow is opposite direction (heads left)
• Anode is + and cathode is -

Question 5

Electrolysis

Similarities in electrolysis cells

Answer 5

Oxidation occurs at the anode

Reduction occurs at cathode
