What is hydration enthalpy? Please explain in a simple manner rather than writing definitions :) |
| Answer» Minimum energy required to add or remove one Water molecule is called hydration enthalpy<br>Thanks a lot<br>\tIncrease in atomic number increases the size of the element which in turn outweighs increasing nuclear charge. Therefore the outermost electron experiences strong screening effect from the nuclear charge.\tThe energy released as a result of the formation of new bonds between ions and water molecules is called hydration enthalpy.\tIn alkali metals the hydration enthalpies decreases with the increase in ionic sizes.\tLi+> Na+ > K+ > Rb+ > Cs+\xa0 | |
