Table 1: tabulated water solubility data
Ca in g/L
SO4 in g/L
The water solubility was determined from the concentration of
calcium as the value calculated by using the solubility of SO4 instead
of Ca produces a slightly higher value, this is due to a small
interference by small quantities of sodium, potassium, magnesium
sulfates explaining this small overestimation.
The water solubility of CaSO4 was determined to be 2.4 g/L at 20°C and
with a pH value of 7.7.
The key study was performed to OECD 105 (non-GLP). It is supported by
several literature and handbook data showing the solubility to be in the
range of 2.34 -2.75 g/L at 20 -25°C.
