What Are the Hazards of Sulfur? | Healthfully

What Are the Hazards of Sulfur?. Sulfur is a chemical element that is nonmetallic. It has a pale yellow color and has no odor. Sulfur in gaseous form combines with oxygen to form sulfur oxide. Sulfur is used to make fertilizer and various types of disinfectant. It is also used in medical laboratories to test skin disease. Sulfur is, however, a hazardous element that should be handled with care.

How does sulphur dioxide react with water? - Quora

Feb 06, 2018· sulphur dioxide is very soluble in water. when water is added to sulphur dioxide ( i.e. sulphur dioxide react with water or rather SO2 is bubbled through water ) , H2SO3 is formed. that is a reason why SO2 is blamed as the key gas for causing acid rain.

Sulfuric acid - Wikipedia

Sulfur dioxide is the main byproduct produced when sulfur-containing fuels such as coal or oil are burned. Sulfuric acid is formed naturally by the oxidation of sulfide minerals, such as iron sulfide. The resulting water can be highly acidic and is called acid mine drainage (AMD) or acid rock drainage (ARD). This acidic water is capable of ...
