PAEZ-MEZA, Manuel Silvestre; ALVARINO-BETTIN, Gustavo Manuel  e  CANTERO-LOPEZ, Plinio de los Santos. Viscosity and viscometric properties of Glycine in aqueous solutions of Sodium Thiosulfate Pentahydrate (Na2S2O3 .5H2O) at different temperatures. Dyna rev.fac.nac.minas [online]. 2014, vol.81, n.186, pp.218-225. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v81n186.40023.

Flowing times of Glycine in aqueous solutions Sodium Thiosulfate Pentahydrate (0.01-2.0 mol kg-1) using an AMVn Anton Paar viscometer at temperatures of (283.15; 288.15; 293.15; 298.15; 303.15; 308.15, 313.15 and 318.15) K and 101.1 Kpa.From the data obtained, the absolute viscosity, viscosity B-coefficients, slope ( ),the  ,adjustable parameters of the equation of Out and  Los ( , , ), activation parameters of viscous flow ( ) were calculated , the values obtained for these parameters were discussed in terms of the interactions present in solution.

Palavras-chave : Viscosity; Activation parameters; Viscous flow; Excess properties; Interactions.
