DESCRIPTION

Sulfur Dioxide occurs as a colorless, nonflammable gas under normal conditions of temperature and pressure. It is shipped as a liquid under pressure in containers approved by the U.S. Department of Transportation. Its vapor density is 2.26 times that of air at atmospheric pressure and 0°. The specific gravity of the liquid is about 1.436 at 0°/4°. At 20° the solubility is about 10 g of Sulfur Dioxide per 100 g of solution.
