ReactionsSulfur forms two oxides, sulfur dioxide, SO2, and the trioxide, SO3. It burns in oxygen at about 250°C or in air above 260°C, forming sulfur dioxide. In excess oxygen the trioxide is obtained. Sulfur reacts with hydrogen at 260 to 350°C forming hydrogen sulfide. The reaction...

This non-metal is pale yellow in appearance, soft, light, with a distinct odor when allied with hydrogen (rotten egg smell). It burns with a blue flame that emits a peculiar suffocating odor (sulfur dioxide, SO2). Sulfur is insoluble in water but soluble in carbon disulfide. Common oxidati...
Sulfur is a chemically active element and forms many compounds, both by itself (sulfides) and in combination with other elements. It is part of many organic compounds, e.g., mercaptans (thiols) and thio compounds. It burns in air with a blue flame, forming sulfur dioxide, SO2. Natural ...
a colorless, nonflammable, water-soluble, suffocating gas, SO2, formed when sulfur burns: used chiefly in the manufacture of chemicals such as sulfuric acid, in preserving fruits and vegetables, and in bleaching, disinfecting, and fumigating. ...
It is a powerful dehydrating agent and oxidizing agent and can cause very severe burns。The dehydrating properties of the concentrated acid can be demonstrated in the laboratory by its reaction with sugar。Sugar is a carbohydrate-it contains carbon,hydrogen and oxygen。The concentrated acid removes ...
Sulfur dioxide is regarded as a substance with good warning properties except in the case of individuals with reactive respiratory tracts and asthmatics. Exposure of the eyes to liquid sulfur dioxide from pressurized containers can cause severe burns, resulting in the loss of vision. Liquid SO2 ...
