Document Summary
Acid rain happens in 2 steps: co2 (g) + h2o (l) = h2co3 (aq, h2co3 (aq) = h+ (aq) + hco3- (aq) this formula is mainly responsible for the creation of acid rain. You have to know that the presence of nox and sox gives a higher acidity, which is a lower ph. Environment effect: (4 of them: material damage: Calcium salts are important to building and statues and acid rain can have a bad effect on them. It will dissolve the calcium on it, thus affecting the surface. Acid rain also badly affect trees by harming the leaves (restricting nutrients to them) Building or any other constructed material that is made of iron will be more affected by corrosion. The reaction of corrosion is as follows: 4fe (s) + 3o2 (g) = 2fe2o3(s) Ph plays an crucial role for water; lakes, oceans (a ph of 6. 5 is the ideal one) A low ph is dangerous for fish species.
