WebJan 4, 2024 · Ans. Enthalpy of hydration is one of the heat changes considered in the computation of electrode potential. Because Li+ is so tiny, it has a very high enthalpy of hydration. As a result, the normal Li+/Li reduction potential is -3.05V. Caesium is the most powerful reducing agent in the gaseous form. WebJun 14, 2014 · Hydration enthalpy is the energy released when one mole of gaseous ions is completely hydrated by water molecules under standard conditions. If two ions of different sizes were surrounded by an equal number of water molecules each, the smaller ion would be more hydrated compared to the larger one due to the size differential.
