VISCOSITY OF THE FOLLOWING NA2CO3, NAHCO3, K2CO3, KHCO3, NA2CO3-NAHCO3 AND K2CO3-KHCO3 SOLUTIONS, IMPORTANT IN ABSORPTION PROCESSES

Data corresponding to the viscosity of Na2CO3, NaHCO3, K2CO3 and KHCO3 aqueous solutions in the temperature range of 293,1 to 323,1 K and to the viscosity of Na2CO3-NaHCO3 and K2CO3-KHCO3 buffer solutions at 298,1 K, with maximum concentrations of 1,5 kmol.m-3 are supplied, because of their importance in the study of gas-liquid transfer processes. The viscosity is related with concentration and temperature and it results the adjustment parameters of the corresponding equations.
