Therefore, acid rain is rain is rain that has been made acidic by certain pollution in the air with a pH from 0-6. Acid rain has a pH of 5.6. Acid rain can appear in wet and dry forms. Rain is always slightly acidic as it mixes with other oxides in the atmosphere. When the air is polluted with nitrogen oxides and sulfur dioxide the acidity can increase to a pH value of 4. Acid rain is formed by pollutants in the air mixing with wet or dry particles. The primary cause of acid rain is industrialization and automotive usage. ]]> 2018-11-27 04:15:23 UTC https://padlet.com/cman2306/mydgcb9sy2e1/wish/308115037 Acid Deposition cman2306 https://padlet.com/cman2306/mydgcb9sy2e1/wish/308116114 Acid Deposition refers to The various processes by which acidic particles such as acidic gases or acidic pre upsets leave the atmosphere. The deposition occurs when nitrogen or sulfur oxides dissolve in water to form HNO3, HNO2, and H2SO3.

human structures built on limestone, easily attacked

by acid

expensive to repair damage from the acid
can create dangerous situations, like bridges falling
world culture at stake, has not dealt with acid rain
Increased risk of respiratory illnesses such as asthma and bronchitis caused by for instance the fine sulfate and nitric particles formed during reactions with acid rain which are able to penetrate the lungs.

toxic soils leaked out of soil damage plant roots

trees more likely to get diseases, drought & insects

Kills trees by taking nutrients away from roots not letting photosynthesis happen

physical damage to leaves and needles

stunts growth of food crops

Nitrogen oxides are produced by the high temperature reaction of of N2 and O2 which are excessively produced by burning plants and automobiles. when Nitrogen dioxide reacts with water, it produces nitric acid and nitric oxide that are oxidized by the atmosphere, creating HNO3.
When Sulfur dioxide and Nitrogen Dioxide react, the product causes emissions to form secondary pollutants sulfuric acid & nitric acids, components of acid rain.
{Nitrogen dioxide} N2 (g) + O2 (g)= 2NO
2NO (g) + O2 (g) = 2NO2 (g).]]> 2018-11-27 04:57:09 UTC https://padlet.com/cman2306/mydgcb9sy2e1/wish/308120755 Reduction of SO2 Submissions cman2306 https://padlet.com/cman2306/mydgcb9sy2e1/wish/310275245 Pre-combustion method: Techniques used on fuels before their combustion.
