Sulfur dioxide

Assignment 7 Power Station Emission Aim: The aim of this experiment is to measure the mass of sulphur dioxide in 1m3 of flue gas (waste gas from burning fossil fuels in a power station). To achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude…

Roof Discolored? Know Three Potential Reasons Why Nobody wants a roof that is a community eyesore with discoloration. Unfortunately, there may be factors at play that are causing this blemish. In order to fix the problem, you must know what is causing it to occur. Here are three reasons why discoloration can happen to a roof. Pigment From Asphalt Shingles There is a process called extractive bleeding where black pigments found in your roof’s shingles can cause a stain to appear. It typically…

Acid rain is a precipitation which falls from the atmosphere to Earth. It contains a high level of nitrous oxide and sulphur dioxide. When they ge tin contact with water they transform to acid in the atmosphere, and then this acid is carried away by the wind thousaands of miles away from where they were created. The acidity is measured with the potential hydrogen (pH) on a scale from 0-14. The pH scale is a logarythmic measure which means that every change in pH is counted in the amount times…

Acid Rain: Pros and Cons Acid Rain. Acid Rain is regular rain fallen from the clouds then made sufficiently acidic by atmospheric pollution. This is created by the process of burning fossil fuels, they contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids. When people hear the words “acid rain” they immediately think about the horrors of it. Few people think about the positive things that acid rain can bring to us. With the evidence given, both sides could be…

The specter of nuclear, biological, chemical (NBC) attack or accident has loomed over our society for generations. Of the family of chemical agents, is the class of vesicants – also known as Blister Agents. Though there are different types of blister agents, their mechanism of action against their victims are the same. A wide spectrum of protective equipment and detection devices are commercially available for first responders in contending with a blister agent incident. Weaponized blister agent…

(s) + H2. This is a single replacement reaction. This reaction most commonly occurs through contact with hydrogen sulfide in the air - although direct contact with substances that contain sulfur can cause tarnishing. Silver tarnishes very quickly when it is exposed to air that contains high levels of ozone, sulfur, or hydrogen sulfide. Silver tarnish appears as a discoloring over the surface of the metal. Rather than the usual shiny or soft appearance of silver, the item’s color could range…

2 SO2 + O2 → 2 SO3 (−99 kJ/mol)The sulphur trioxide is hydrated into sulphuric acid H2SO4:SO3 + H2O → H2SO4(g) (−101 kJ/mol)The last step is the condensation of the sulphuric acid to liquid 97–98% H2SO4:H2SO4(g) → H2SO4(l) (−69 kJ/mol) The Extreme Health Hazards Associated with Sulphuric AcidConcentrated sulphuric acid is extremely corrosive. Nott only being a cause of chemical burns, this chemical also causes second degree burns as a consequence of dehydration. This chemical is able to corrode…

ABSTRACT: Acid mine drainage has a prominent and damaging effect on the environment. This paper outlines the environmental impact, the chemistry behind the acid generation, and methods of treatment. The objective of this paper is to educate the reader about acid mine drainage, and what can be done to reduce this pollutant. INTRODUCTION/BACKGROUND: Acid mine drainage (AMD) often occurs at abandoned mining sites. Acid generation is the result of combining certain minerals, water, and an oxidant.…

Equilibrium Paper There are multiple ingredients used to make baked goods rise; baking powder and baking soda are among them. The difference between single and double-acting baking powders is simple. Single-acting releases the carbon dioxide bubbles when mixed with a liquid ingredient and double-acting soda releases bubbles when the baked item is placed in heat. Baking soda and baking powder are remarkably similar, yet there are distinct differences. One is that baking soda is a strong base,…

Coal power plants are one of the top polluting sources of carbon dioxide in the world, just behind vehicle emissions. The article ‘Coal power: pollution, politics, and profits’ states that the “Negative health effects on the nearby human population, plant life, and wildlife have been hard to quantify precisely and thoroughly, and are generally not included in the cost of coal power to the consumer” (Laskowski). Due to this, the general population is not aware of how destructive this power source…
