Igcse Model Questions Vol1 2018 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2018 Igcse Model Questions Vol1 Chemistry examination.
A copper electroplating cell operates at a constant current of \(2.0\ \text{A}\) for \(3\) hours. Only \(85\%\) of the current is used for the reduction of copper ions, the remainder producing hydrogen gas. Using Faraday's law, calculate the mass of copper deposited on the cathode. (Molar mass of Cu = \(63.55\ \text{g mol}^{-1}\), \(n = 2\) electrons per Cu atom, Faraday constant \(F = 96\,485\ \text{C mol}^{-1}\)).
