Hi Folks, I might have been wrong in including the solvated layer in the effective ionic radius of silver ions, although I am sure I read this somewhere.
Any way, this link provides the method and solves the question of the radius of Ag+ in water..... 0.149 nm http://www.tannerm.com/electrochemistry/ion_speeds/IonSpeeds.htm It is actually worth looking at this whole section : http://www.tannerm.com/electrochemistry/electrochem.htm Ivan. ----- Original Message ----- From: "James Osbourne, Holmes" <[email protected]> To: "'James Allison'" <[email protected]> Cc: "'Silver List'" <[email protected]> Sent: Friday, 2 June 2000 18:59 Subject: RE: CS>Dr Clark on CS > Hi James, > > The ionic radii vary with state and environment.
