Solubility Data: Na2SO4
Aqueous solubility of inorganic compounds, organic compounds, and sugars vs temperature (0–100°C). Inorganic compounds in g per 100 g water (CRC Table 5-167, 290+ compounds); organic compounds in g per 100 g water converted from g/kg (CRC Table 5-139, 1200+ compounds); selected salts also have mol/L values (CRC Table 5-179). Used in crystallization design, mass transfer calculations, precipitation reactions, and environmental chemistry.
