Igcse Model Questions Vol1 2021 Chemistry Question 16
Practice objective / multiple choice question 16 from the 2021 Igcse Model Questions Vol1 Chemistry examination.
A copper electrode is placed in a copper(II) sulphate solution and connected to a power supply that delivers a constant current of \(2.0\ \text{A}\) for \(30\ \text{min}\). The current efficiency for the deposition of copper is \(85\%\). Calculate the mass of copper that is actually deposited on the electrode. (Molar mass of Cu = \(63.55\ \text{g\ mol}^{-1}\), Faraday constant = \(96485\ \text{C\ mol}^{-1}\).)
