Disproportionation & Electrode Potential A?disproportionation?reaction is where one element in a chemical is simultaneously reduced and oxidised, e.g. 2Cu+?(aq) → Cu2+?(aq) + Cu (s) Stan...
Thermodynamic Feasibility Feasibility The?E??values of a species indicate how?easily?they can get?oxidised?or?reduced The?more?positive the value, the easier it is to reduce the species on t...
Conventional Cell Representation Conventional Representation of Cells As it is cumbersome and time-consuming to draw out every electrochemical cell in full, a system of notation is used whic...
Measuring Standard Electrode Potential There are three different types of half-cells that can be connected to a standard hydrogen electrode to measure standard electrode potential A metal / ...
