La parte central de la provincia de Santa Fe (Argentina) es un área de llanuras, con pendientes muy bajas con predominio del movimiento vertical del agua sobre el horizontal. Es el caso de la cuenca del arroyo Los Padres (670 km2) donde se implement

Density and viscosity of (water + acetonitrile) mixtures were measured over the whole composition range at the temperatures: (298.15, 303.15, 308.15, 313.15, and 318.15) K. A new mathematical approach was developed which allows the calculation of the

Ionic association between Cu2+(aq) and SO 4 2 - ( aq ) has been studied in the temperature range (298 to 473) K using a spectrophotometric technique. Experiments were designed to minimize the contribution of other protolytic equilibria in solution. T

The dissociation equilibrium of 4-methylphenol in aqueous solutions has been studied spectrophotometrically over the temperature range 298 to 448 K; at higher temperatures the anion decomposed appreciably. The solutions that were studied had differen
