Abstract
Results of new relative measurements of the density and viscosity of aqueous solutions of Na2CO3 and K2CO3 at atmospheric pressure are presented. The temperature ranged from 20 to 60°C, and the composition ranged from pure water to near saturation. All the data have been correlated with the aid of double polynomials. Owing to some evidence of chemical attack of the borosilicate viscometers, the accuracy of the viscosity measurements is estimated to be ±1%, whereas that of density is estimated to be ±0.01%.
