Challenge Problems
Push your limits with challenges.
Question 1
Calculate the amount of hydrogen gas produced in the electrolysis of water when 2.0 A of current is passed for 10 minutes. Given the molar volume of hydrogen at STP is 22.4 L.
💡 Hint: Q = It; moles of gas = Q/F; where F is Faraday's constant.
Question 2
A metal A is deposited by electroplating from an electrolytic cell. If 5.0 grams of metal A is deposited when 10 C is passed through the cell, what is the equivalent weight of metal A?
💡 Hint: Remember that the formula relates mass deposit to charge.
