Challenge Problems
Push your limits with advanced challenges
In an electrolytic cell, a current of 3 A is maintained for 1.5 hours. If the electrolysis leads to the plating of silver and the charge needed to plate 1 mole of silver is 96500 C, calculate the moles of silver deposited.
💡 Hint: Use the relationship from Faraday’s First Law.
If an unknown electrolyte deposits 5 grams of a substance after passing 1.2 x 10^5 C, can you determine the constant k if the substance has a molar mass of 40 g/mol?
💡 Hint: Make sure to relate mass to the total charge passed.
