Point 1: Why I choose acid rain:
I choose acid rain for my project because I wanted to understand better how the rain becomes to an acid and why it is such a big issue for nature.

All of the reactions present are synthesis reactions. This means that, in this case, two reactants react to form one new product. In the first equation, gaseous sulfur dioxide reacts with liquid water to form aqueous sulfurous acid. The second reaction includes two equations. In the first equation, sulfur dioxide gas reacts with oxygen gas to form gaseous sulfur trioxide. This reaction is catalyzed by dust and smoke particles. Then the sulfur trioxide reacts with water to form sulfuric acid, a much stronger acid than sulfurous acid. In the last equation, gaseous nitrogen dioxide reacts with liquid water to form a mixture of aqueous nitric acid and aqueous nitrous …show more content…
The cause was then unclear. In 1872, the English scientist Angus Smith first used the term acid rain after observing acidic precipitation. Acid rain was not really a problem until the 1970s. Lakes and rivers became during that time period significantly more acetic. The reason was that power plants used coal with a higher amount of sulfur as fuel.

Point 7: Acid rain today
Lakes and rivers in Europe and North America have significantly lower pH-values than 7. Plants and animals are not used to different pH-values of water and will die because of acidic properties. The acid rain also affects buildings, statues and sculpture. The acid rain reacts with the stone or metal and destroys it. The only real way to reduce acid rain is to reduce the amount of sulfur dioxide and nitrogen oxides produced. This can be achieved by using alternative energy sources. The EPA (Environmental Protection Agency) created policies about sulfur dioxide and nitrogen oxides to reduce effects of acid rain.
