Assembly of a Robust and Economical MnO2-Based Reference Electrode

摘要: There is a dearth of base-stable reference electrodes that are suitable for use by students in teaching laboratory or undergraduate research context. To remedy this, we have developed technique to produce alkaline environments. By utilizing components commercially available alkaline-type battery, an engineered MnO2/MnO(OH) cathode both stable and reproducible readily obtained. The electrode potentials quite with respect time depend on the state charge battery used make electrode. assembly such easily lends itself introductory electrochemistry lab experiments at fraction cost traditional electrodes.
