Abstract

Measurements of viscosity with varying concentration of solute, added sodium chloride, and the extent of neutralization of the solutions of gum arabate and arabic acid have been reported. A connected explanation for all the different observations has been formulated by the assumption of the existence of flexible chain molecules in solutions of gum arabate. From the same considerations the effect of pH variation with alkali on the relative viscosity of gum arabate solution has been attributed to the effect of sodium ion from alkali rather than the particular pH value.
