WebSince the radii of hydrated ions are significantly (almost twice) larger than the radius of a water molecule (0,138 nm) passed through the membrane, then the estimation of the size of hydrated ions, the components of sea water (mainly: Na+, K+, Mg2+, Ca2+, Cl–, SO42–) for the manufacture of membranes with optimal size becomes meaningful because … 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 … Meer weergeven Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge.
