Sodium sulfate solubility curve

This post was last edited by sunjl1981 on 2013-1-6 21:33. There is an urgent need for the solubility curve of sodium sulfate in sodium chloride solution. The ideal temperature is between -10°C and 0°C. The concentration of the sodium chloride solution ranges from 10% to 30%. Thank you # + +. hcbbs
Please refer to Handbook of Physicochemical Constants for the Chlor-alkali Industry, pages P27–28; it’s too troublesome to type it out! ! !
