To do this, add 2 cups, or about 475 grams (g), of Epsom salt to the water in a standard-sized bathtub and soak your body for at least 15 minutes. MgSO4.xH2O. Materials: - Crucible with a lid - Tongs - Spatula - Bunsen burner - Pipe clay triangle - Balance - Chemicals: - Epsom salt (magnesium sulfate heptahydrate) - 6 M . We do this by subtracting the mass of the anhydrate from the mass of the hydrate. Epsom salt can be taken by mouth as a magnesium supplement or as a laxative. The second part of the name begins with a prefix. Open Document. It is because hydrates are capable of infusing moisture into the skin. Hydrated salts naturally occur all over the world -- including in freshwater. The mass of the sample after complete dehydration was 2.41 g.
