WebThe best-known laboratory function of magnesium sulfate has a strange echo of those purgative origins. This is pure magnesium sulfate, without any attached water molecules and hence anhydrous. This form of the compound will rapidly grab any nearby water molecules. In damp air, the white powder rapidly deliquesces. WebOct 5, 2013 · For example, adding 50 mL of ethanol to 50 mL of water will result in a total volume that is less than 100 mL. It is actually closer to 96 mL. Therefore, when preparing volume/volume percent solutions, it is always better to dissolve the solute in solvent and then add additional solvent to bring the total solution volume to the desired final value.
