Standard reduction potential of alkali metals
WebbAlkali metal ions -- on the very left edge of the periodic table, such as potassium or cesium -- have very negative reduction potentials. These ions are very difficult to reduce. WebbStandard reduction potentials are determined by connecting the system represented in the half-reaction equation concerned to a standard hydrogen electrode via a salt bridge and reading off the potential difference on either a previously calibrated potentiometer or a high resistance voltmeter.

WebbM (s)→ M (g) Sublimation enthalpy. M (g) → M +(g)+ e− ionization enthalpy. M +(g)+ H 2O → M +(aq) hydration enthalpy. With the small size of its ion, lithium has the highest hydration enthalpy which accounts for its high negative E ∘ value and its high reducing power. Hence, the order of reducing character of alkali metals is N a < K ... Webb20 feb. 2015 · Alkali metals act as strong reducing agents as their ionization energy values are low. Since, ionization decreases on moving down from Li to Cs, the reducing property increases in same order. Thus, Li is the weakest reducing agent while Cs is the strongest reducing agent amongst alkali metals in free gaseous state.
