Solubilities of carbon dioxide and densities of aqueous sodium glycinate solutions before and after CO absorption

The densities of aqueous solutions of sodium glycinate (SG) were measured for a range of concentrations [(1, 5, 10, 15, 20, and 30) % wt] and at a temperature range (298.15 to 353.15) K. The solubility of CO2 in aqueous solution of sodium glycinate was measured for the same concentration range and...

It was found that density of aqueous solutions of sodium glycinate increases as the molar concentration increases and decreases with an increase in temperature.
