Course # Student name / Names of members of group Date: Exp # : Estimating the effects of acid rain Introduction: Precipitation that measures a pH value below 5.6 is generally considered as acid rain. Burning fossil fuels is the main reason for the elevated levels of gaseous oxides in a polluted atmosphere that in-turn forms acid rain. Gaseous oxides such as that of carbon, sulfur, nitrogen and phosphorus could dissolve in water to form an acidic solution. A generalized reaction sequence on the formation of acid rain is as follows; One of the determinants of clean water in the natural environment is its alkalinity. Alkalinity can be defined as the capacity to neutralize acids.
Lab 5: Precipitate Patterns October 31st, 2013 Partners: Muhammad Saeed, Kristian Palmer and Kyle Poirier By: Rauman Tuan-Kichil For: Mr. Fontaine Investigation: Wastewater from metal manufacturing processes often contains toxic cations. These ions must be removed before the water can be released into the environment. Many of these ions can be removed using precipitation reactions. For example, recycled car batteries contain toxic lead cations, Pb 2+. These can be removed by adding a solution of potassium iodide, KI.
Some mining involves the inadvertent dispersal of heavy metals, such as lead, into the atmosphere. This can have serious health effects 4. What can be done to prevent mine drainage from damaging the ecosystem? Utilize at least one scholarly resource to support your suggestions. Answer = According to World Coal, there are mining
Ryan Agro Acid Rain Lab Purpose: I.V: Type of Stone D.V: Mass of rock after 5 days Control: Stone in Water Problem Statement: Acid rain causes some stones to loose mass. Which type of Stone is the best to prevent a loss in mass? Hypothesis: If the material used is affected by acid rain, then it will lose mass when exposed o vinegar, because of chemical changes. Procedure: 1. Gather Materials(container with lid, graduated cylinder, vinegar, balance, limestone, marble, red sandstone, granite) 2.
The wind blows these acidic gases into building, cars, homes and trees. Water that runs of these buildings adds acid to the acid rain, making the combination more acidic than regular rain. Acid rain is measured by a pH scale, the lower the number, the more acidic, Vic versa. The effects of acid rain are, damages of forest soils, fish and other living organisms, it also affects lakes, streams and causes aluminum to be highly toxic to species and aquatic organisms. In North America acid rain affects the Adirondack and the Catskill Mountain in the state
Sulfuric Acid is a strong acid that exists as a colorless oily corrosive liquid and is made by reacting sulfur trioxide with water. This is most commonly found in batteries, manufacture of fertilizers, explosives, detergents, dyes and other different chemicals. Sulfuric Acid is very dangerous to humans as it can cause respiratory tracts of humans and other animals while doing some major damage to plants that helps provide oxygen for us. Ground-level ozone is a secondary air pollutant formed when sunlight triggers reactions between nitrogen oxides and volatile hydrocarbons. If a human inhales ground-level ozone it can cause chest pain, throat irritation, and congestion.
C. mixing very weak acids. D. heating small quantities. ID:57858 A 3. Since some power plants are built near the ocean, they can pollute the water. One way this occurs is when warm wastewater is pumped into cool seawater, killing cool-water organisms.
When the hydrate is heated, it easily loses water molecules attached and becomes an anhydrous salt. The corresponding chemical reaction for hydrated magnesium sulfate can be written as |MgSO4•7H2O ( MgSO4 + 7H2O |(1) | where MgSO4 is the anhydrous salt. Usually,
This means that it can be very dangerous if kept in powdered form. The environmental benefits and limitations of Zirconium Zirconium has a concentration of 0.026 μg/L in sea water, and is first collected from coastal waters as the solid mineral zircon. Excess sand and gravel are removed using apparatus called a spiral concentrator. Magnetic seperators remove ilmenite and rutile. The product of this process is then purified by chloride.
The Hazards of Welding Fumes for the Different Metals and their Symptoms | In this paper I hope to show some of the hazards that are associated with being exposed to some of the different types of fumes produced while welding. The hazardous effect of welding fumes and gases on a welder's health can vary with the different types of metals, the length, the amount of the exposure, and the specific toxicity of the metals involved. The welding process involving stainless steel involves, cadmium- or lead-coated steel, or metals such as nickel, chrome, zinc, and copper can be hazardous as the fumes produced have a higher toxicity level than those which a welder breaths when welding mild steel. Mild steel will consists mostly of iron, carbon, and small amounts of manganese, phosphorous, sulfur, and silicon. While stainless steel consists’ mainly iron, chromium, nickel, titanium, and manganese.
