    “Acid Rain” Environmental science What is Acid Rain? Acid rain is a rain or any other form of precipitation like rain‚ fog‚ snow‚ or hail that contains harmful substances higher than normal amounts of such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs

    that had been used to make the structures. Marble and limestone used to be very common materials for art that was meant to be exposed outdoors. To a surprise‚ the acid rain could turn the calcium carbonate molecules that were found on these stone materials into calcium sulphate molecules. This is the result of calcium sulphate being dissolved by water; acid rain would eventually wash away the outside layer of buildings and statues. There are many examples all across the world of the corrosive effects

    They produce large mounds of calcium carbonate‚ much like tropical corals‚ although at a much slower rate than the tropical corals. Contrary to public belief‚ it is the “deep-water coral communities that will first to experience a shift from saturated to undersaturated conditions of calcium carbonate” (Doney‚ 24). Organisms that produce aragonite are more vulnerable to changes in ocean acidity than those that produce

    be made‚ as our results were not as accurate as we would have liked them to be. These improvements include being more careful when measuring out the hydrochloric acid in the graduated cylinder‚ putting the lid of the tube on faster right after the calcium chloride has been added so that no gas produced can escape‚ and making sure the very fine grains do not get stuck on the tube instead of going all the way down the tube into the hydrochloric acid. The rate of a chemical reaction is the speed at which
