1. Which of the following statements is true regarding the anode in an electrolytic cell?
It is the site of reduction.
It is negatively charged.
Oxidation occurs at the anode.
Cations migrate towards it.
2. What is the SI unit for electric charge in Faraday's Law calculations?
Ampere
Volt
Coulomb
Joule
3. Electrolysis is a process that uses energy to drive a non-spontaneous chemical reaction.
4. Faraday's First Law of Electrolysis states that the mass of a substance deposited or liberated at an electrode is directly proportional to the passed through the electrolyte.
5. The amount of electricity required to deposit one mole of a monovalent ion is approximately Coulombs.
6. Briefly explain the difference between an electrolytic cell and a galvanic (voltaic) cell.
7. State Faraday's Second Law of Electrolysis.
8. A current of 5.0 A is passed through a solution of copper(II) sulfate for 30 minutes. Calculate the mass of copper deposited at the cathode. (Molar mass of Cu = 63.55 g/mol, 1 F = 96485 C/mol e-)
9. How long will it take to deposit 10.0 g of silver from a silver nitrate solution using a current of 2.0 A? (Molar mass of Ag = 107.87 g/mol, 1 F = 96485 C/mol e-)
10. In an electrolytic cell, the cathode is always negatively charged.
True
False
11. Faraday's constant represents the charge carried by one mole of electrons.
True
False
