Web29 apr. 2024 · 2.3.1 Two Techniques for Inert Atmosphere Experiments. Electrochemical experiments in an inert atmosphere can be performed either on the benchtop or within a glovebox (see Sections 3 and 4, respectively). Conducting an electrochemical experiment in the absence of oxygen is much simpler than in the absence of water. WebOnce copper (II) nitrate has been electrolysed (preferably last), a deposit of copper will have formed on the cathode. This has to be removed before the cells can be used again. Immersing the plated part of the electrode in a small quantity of 50% concentrated nitric acid (CORROSIVE) in a small beaker can be used to do this. twodime llp
