Acid Rain Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5.6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of sulfuric acid, some of its uses and the effects of it as a pollutant in our environment. Sulfuric Acid Industry in Ontario Among the many plants in Ontario where sulfuric acid is produced, there are three major plant locations that should be noted on account of their greater size. These are: Inco. - Sudbury Noranda Mines Ltd. - Welland Sulfide - Ontario There are a number of factors which govern the location of each manufacturing plant. Some of these factors that have to be considered when deciding the location of a Sulfuric Acid plant are: a. Whether there is ready access to raw materials; b. Whether the location is close to major transportation routes; c. Whether there is a suitable work force in the area for plant construction and operation; d. Whether there is sufficient energy resources readily available; e. Whether or not the chemical plant can carry out its operation without any unacceptable damage to the environment. Listed above are the basic deciding factors that govern the location of a plant. The following will explain in greater detail why these factors should be considered. 1) Raw Materials The plant needs to be close to the raw materials that are involved in the production of sulfuric acid such as sulfur, lead, copper, zinc sulfides, etc.. 2) Transportation A manufacturer must consider proximity to transpor-tation routes and the location of both the source of raw materials and the market for the product. The raw materials have to be transported to the plant, and the final product must be transported to the customer or distributor. Economic pros and cons must also be thought about. For example, must sulfuric plants are located near the market because it costs more to transport sulfuric acid than the main raw materials, sulfur. Elaborate commission proof container are required for the transportation of sulfuric acid while sulfur can be much more easily transported by truck or railway car. 3) Human Resources For a sulfuric acid plant to operate, a large work force will obviously be required.

In this essay, the author

  • Explains that acid rain has become an environmental concern of global importance within the last decade.
  • Explains that there are three major plant locations in ontario where sulfuric acid is produced — inco. - sudburynoranda mines ltd.
  • Explains the basic deciding factors that govern the location of a chemical plant.
  • Explains that the plant needs to be close to the raw materials that are involved in the production of sulfuric acid.
  • Explains that a sulfuric acid plant must employ chemists, technicians, administrators, computer operators, and people in sales and marketing.
  • Explains that proximity to a plentiful supply of energy determines the plant's location. environmental concerns must be carefully taken into consideration.
  • Explains that the closeness of the plants to water supplies is another factor, as many manufacturing plants use water for cooling purposes. land is available at a reasonable cost, climate is suitable, and living conditions are suitable for people relocating in the area.
  • Explains that the final decision on where the sulfuric acid plant really involves a careful examination and compromise among all the factors that have been discussed above.
  • Explains that the product of the contact plants is 98-100% acid, which can either be diluted to lower concentrations or made stronger with sulfur trioxide to yield oleums.
  • Explains that the battery acid industry relies on sulfuric acid to produce power. all batteries, primary or secondary, work as result of a chemical reaction.
  • Explains that a battery cell consists of three basic parts: positively charged electrode, anode, and electrolyte, in which the electrodes are immersed.
  • Explains that electricity is generated in cells because when chemical substances are dissolved in water, their molecules break up and become electrically charged ions.
  • Describes the charging and discharging phase of the lead-acid storage battery and how sulfuric acid, as the electrolyte, is used in the process.
  • Explains that the concentration of sulfuric acid is 0.0443 mol/l. the ph is 1.05. the amount of base needed to neutralize the lake water is
  • Compares the use of sodium hydroxide versus limestone to neutralize the lake water.
  • Explains that water is produced when using sodium hydroxide. liming is another way to neutralize a lake.
  • Explains the effects of acidification on aquatic living organisms, such as zooplankton, algae, and bacterial decomposition of dead matter.
  • Explains that excessive acidic conditions affect aquatic organisms and animals, since few aquatic plants survive in such conditions. anything affecting one organism affects the food chain.
  • Explains the factors that govern a plant's location, if it employs 40% of the townspeople, such as ready access to raw materials, proximity to major transportation routes, energy resources, and adequate water supply.
  • Explains that pollution in the great lakes has become an increasingly serious problem.
  • Opines that pollution problems could be fought under a three-stage plan over the next decade: 1) a "toxic freeze" banning new polluters from putting up pipes or smokestacks
  • Explains the advantages and disadvantages of water treatment devices and purifiers.
  • Describes the key events in the u.s.-canada relationship regarding the great lakes cleanup.
  • Explains that canada and the united states agreed to zero discharge of pollution in 1978. mulroney also proposed that the u.s. slash industrial sulfur and nitrogen oxide emissions by half.
  • Explains that the canada-u.s. international joint commission meets every two years to discuss pollution and other issues concerning the great lakes.
  • Cites encyclopedia britannica, science & technology illustrated: the world around u.s., volume 3, and newsweek's "deadline urged for cleanup of great lakes".
  • Narrates the globe and mail's "great afflictions of the great lakes" and "the clean water industry grows on fear.
  • Cites the globe and mail, sanderson, kimberly, the new how it works, and weller, phil.
