怎样比较离子水合半径的大小
答
For ions with the same charge, such as Li+ and K+, small ion has larger size of hydrated ion. This is due to the its larger charge density, and hence, larger coulombic force with water molecules.
For ions with different charges, such as Mg2+, and Li+, larger of the charge, smaller size of the hydrated ion.
