WebMay 29, 2024 · For hydration energy and cations of the similar kind, like alkali metals, smaller the radius, bigger hydration energy, as there is stronger electrostatic fields. It has e.g. direct impact on ion mobility and conductivity. For different kinds of captions, the electrophilic affinity of cations plays role as well. WebWe know the hydrated radius is defined as the radius of ions and closely bonded water molecules. This means that the hydrated radius is the radius of ions when surrounded by water molecules. The energy released when an ion is hydrated i.e. accepts water molecules is known as hydration energy. What is hydrated ion?
Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 31 pm (0.3 Å) to over 200 pm (2 Å). WebThe true radius of the ion in solution is the hydrated radius, which is the effective size of an ion or a molecule plus its associated water molecules in solution Larger radius of naked...
