Conductances of electrolytes in solutions of the sucrose polymer Ficoll

Abstract

The limiting equivalent conductances of several electrolytes have been measured at 25° in aqueous solutions of the synthetic sucrose polymer Ficoll. Though the viscosity of the solutions is several times that of sucrose solutions of the same percentage by weight of solute, the limiting conductances of small ions in them are little different from those in sucrose solutions. It is concluded that the polymer molecules form loose networks to a large extent permeable to small ions.
