Solution: An acidified solution was electrolyzed using
Chapter 18, Problem 18.86(choose chapter or problem)
An acidified solution was electrolyzed using copper electrodes. A constant current of 1.18 A caused the anode to lose 0.584 g after 1.52 3 103 s. (a) What is the gas produced at the cathode and what is its volume at STP? (b) Given that the charge of an electron is 1.6022 3 10219 C, calculate Avogadros number. Assume that copper is oxidized to Cu21 ions.
