Rain
Acid Rain Introduction Acid rain has become an environmental concern of global importancewithin the last decade. With the increasing environmental awareness of the "unhealthy" conditionof our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pHvalues of less than 5.6. When dealing with acid rain one must study and understand the process ofmaking Sulfuric acid. In this project we will take an in depth look into the production of sulfuricacid, some of its uses and the effects of it as a pollutant in our environment. Sulfuric AcidIndustry in Ontario Among the many plants in Ontario where sulfuric acid is produced, there arethree 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 whichgovern the location of each manufacturing plant. Some of these factors that have to be consideredwhen deciding the location of a Sulfuric Acid plant are: a. Whether there is ready access to rawmaterials; b. Whether the location is close to major transportation routes; c. Whether there is asuitable work force in the area for plant constructi
In either a wet or dry cell, sufficient liquid must be present to allow thechemical reactions to take place. A battery can be primaryor secondary. Battery Acid IndustryMany industries depend on sulfuric acid. 6 million people depend on Lake Ontario alone for drinking water. Chemicals that exist in low levels in the airand water accumulate as they move up through the food chain. "Great LakesPollution as a Political Issue", The Globe and Mail, Oct. Manyfilters use some form of "activate" carbon. Others Countdown Acid Rain, Facts: Ministry of theEnvironment, 1989. The equation for the neutralization usinglimestone is as follows: Ca CO3 + H2SO4 AAAA* CaSO4 + H2O. A large number of workers will also be required for the daily operation of theplant. The following will describe both the charging and discharging phase ofthe lead-storage battery and how sulfuric acid, as the electrolyte, is used in the process. Limestone also does not dissolve as readily as sodium hydroxide thus taking a longer period oftime to react with sulfuric acid to neutralize the lake. 5) Environmental Concerns Most importantly,however, concerns about the environment must be carefully taken into consideration.
