colorless and corrosive. Sulfuric acid is used with varying degrees of concentrations in manufacturing processes and in petroleum refining. When sulfuric acid is heated it decomposes into water and sulfur trioxide. Sulfuric acid is very strong and a great oxidizing agent. It reacts readily with carbon‚ sulfur‚ and metals when it is at high temperatures (The Editors of Encyclopedia Britannica‚ 2014). Sulfuric acid will cause severe burns with any method of exposure and may be fatal if it is inhaled. It

Scrubber systems In short a scrubber system basically removes harmful materials from exhaust gases before they are released into the environment or atmosphere. There are two types of scrubbing methods. There is wet and dry scrubbing. Both systems work in similar ways and have the same end result. That is to change a toxic chemical into something less toxic or non-toxic. Now scrubber systems rely on a chemical reaction with a sorbent (which is a material that sorbs another substance or A substance

Atmospheric Issues SCI/275 For several years‚ we have been aware of the harms we produce to the environment‚ and yet we keep on creating them. Some people are more familiar than others about these harms. However‚ it seems as if there is no concern since change is happening slowly. Around the globe similar harms exist. Some are even more advanced in some places. We can clearly see the consequences of these harms. They are drastically disturbing our environment. The sufferers from these events

with a pH of 5.6. Humans or natural occurrences can cause acid rain. For example‚ when a volcano erupts‚ it releases sulfur dioxide as one of the main components‚ which can enter the water and cause it to become acidic. However‚ the primary source of acid rain is the acidic compounds released by atmosphere pollution. Industrial processes like factories and motors like cars release sulfur dioxide (SO2) and nitrogen oxide and dioxide (NO2 or NO3‚ commonly written as NOx)‚ which are both strong acids when

Bacteria are often maligned as the causes of human and animal disease (like this one‚ Leptospira‚ which causes serious disease in livestock). However‚ certain bacteria‚ the actinomycetes‚ produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies‚ or on the roots of certain plants‚ converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to break

Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops

What it is: • the deposition of acidic components in rain‚ snow‚ dew‚ or dry particles. • more accurate term is "acid precipitation." • defined as any type of precipitation with a pH that is unusually low The Causes: • occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere‚ undergo chemical transformations and are absorbed by water droplets in clouds • then fall to earth as rain‚ snow‚ mist‚ dry dust‚ hail‚ or sleet. • Dissolved carbon dioxide dissociates to form weak

many sensitive forest soils. In addition‚ acid rain accelerates the decay of building materials and paints‚ including irreplaceable buildings‚ statues‚ and sculptures that are part of our nation’s cultural heritage. Prior to falling to the earth‚ sulfur dioxide (SO2) and nitrogen oxide (NOx) gases and their particulate matter derivatives—sulfates and nitrates—contribute to visibility degradation and harm public health. Acid rain causes acidification of lakes and streams and contributes to the damage

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a
