Abstract
The relative viscosity data of sodium and potassium halides (concentration range 0.125–3 M) in aqueous urea (1.0 M) solution at the temperature 25°, 30°, 35° and 40°C have been determined. The data have been found to satisfy Moulik's equation, for concentrated solution of the alkali halides beyond the Einstein's region. Furthermore the “effective” rigid molar volume V e and the apparent B coefficient have been computed employing Breslau and Miller treatment from the relative viscosity data. On the basis of apparent B coefficient values obtained for different temperatures, it has been observed that both sodium and potassium halides in aqueous (1.0 M) urea solution show structure breaking trend.
