Expert Answer
M→M2+
M2+→M3+
The above equations signify the standard electrode potentials of some half–cells involving 3d-series of transition elements and their ions in aqueous solution,
Electrode potential for a Mn+/M half-cell is a measure of the tendency for the reaction, Mn+(aq) + ne– → M(s)
Look out at this series:
Standard electrode potentials for 3d-elements
The above transition series explain the trends of d- block elements in which the negative values of E° for the first series of transition elements (except for Cu2+/ Cu ) indicate that metals should liberate hydrogen from dilute acids i.e., the reactions.
