Relative viscosities of NaCl, KCl, KBr, RbCl, KI in 10% (W/W) 2-(Ethoxy) ethanol - water mixture are measured at 30^o , 35^o and 40^oC. Joules-Dole equation is used to analyze the data to calculate B-coefficients. Transition state theory is applied to calculate Enthalpy activation of viscous flow (  H^-₂^0# ) and entropy of activation of viscous flow ( S₂^0# ). The temperature coefficients of ( H₂^0# ) ,       (  S₂ ^{0 #}) and B-coefficients show that in the present solvent system Na⁺ is a structure making ion while K⁺. Rb⁺, Cl^-, Br^-, I^-   are structure breaking ions. An attempt is made to split the enthalpy and entropy values of the electrolytes into their ionic contributions. Solute-solvent interaction parameter ( )  , solvation numbers and ionic volumes are also calculated. These values support the conclusions drawn from H^-₂^0#  and S₂^0# . Dimensions of the ions are calculated from the viscosity B-coefficients and are compared with Pauling’s crystal radius of the ions.
