Question 1

What does Faraday's Second Law state about mass deposition during electrolysis?

  • It is independent of time.
  • It is proportional to the charge passed.
  • It is proportional to temperature.
  • None of the above.

💡 Hint: Think about what variables affect deposition during electrolysis.

Question 2

True or False: Faraday’s Second Law can be used to predict the mass of different substances deposited for the same charge.

  • True
  • False

💡 Hint: Consider how equivalent weights come into play.

Challenge Problems

Push your limits with challenges.

Question 1

A current of 1.5 A passes through an electrolyte for 15 minutes. Calculate the mass of copper deposited if the equivalent weight of copper is 31.75 g/equiv.

💡 Hint: Use the charge calculation to apply it to the mass deposition.

Question 2

In a laboratory, an experiment is conducted where various salts are electrolyzed for the same charge. If 0.5 g of lead is deposited, find out how much barium weighs if its equivalent weight is 137 g/equiv.

💡 Hint: Set up the ratio based on their equivalent weights to find the mass of Barium.
