Solubility data for use in the assessment of the drowning-out precipitation of magnesium sulfate heptahydrate in aqueous ethanol over the temperature range 15-35-degrees-C and the densities of the resulting saturated solutions are reported. In all cases, the presence of ethanol significantly reduces both the solubility and density of magnesium sulfate heptahydrate in aqueous solution. The solubility data may conveniently be expressed by a relationship of the form in W(eq) = A + Bx + Cx2 + Dx3 with an accuracy +/- 2% where W(eq) is the equilibrium saturation concentration of magnesium sulfate heptahydrate, expressed as kg of magnesium sulfate (hydrate)/100 kg of free water, and x is the concentration of ethanol expressed as kg ethanol/kg of free water.
