Sulfur Dioxide to Sulfur Trioxide
By: Uziel Pecina
Sulfur Dioxide
It is an colorless and has a irritating, choking odor. It is produced naturally in volcanoes and geysers. It is also produced by the burning of coal containing sulfur. Sulfur dioxide is also the main contributor to Acid rain. This is a bad thing to the Earths ecosystem because of Sulfur Dioxide. It can react with water to make sulfurous acid (moderately strong acid).
Sulfur trioxide
Sulfur Dioxide mixed with Oxygen can produce this gas which then reacts with water to produce Sulfuric Acid which is the man contributor to Acid rain. In order to help the ecosystem we must reduce the emission of Sulfuric Acid by using low sulfur coal. Most factories now use scrubbers, which puts sulfur oxide in contact with calcium oxide to produce solid calcium sulfite. This prevents the sulfur from going into the atmosphere.
Good Things
Pros
- Sulfur Dioxide is used widely to prevent dried fruits from losing their colors.
- Also used to Bleach Vegetables
- And used to prevent wines from turning brown and discolored.
- In the food industry, it is used as a disinfectant during the manufacturing process.
Bad Things
Cons
- Sulfur Dioxide and Oxygen will both mix to produce Sulfur trioxide. when Sulfur is emitted into the atmosphere, it can cause Acid rain.
- Plants exposed to Sulfur Dioxide can lose their foliage or become less productive.
- It can reduce lung function in the air
- is not good for Asthmatics and other with respiratory problems
Chemical Shift Due to increase in Temperature
- Is exothermic
- Will shift to the left if heat added
Increase in Pressure
- Reaction will shift to the products
- Because it has least amount of moles
Increase in Concentration of Reactant
- Will shift to the products
- because it will use up the "excess" of the equilibrium.
