Impressions after reading "Exploring the Weather"
The air cannot be seen or touched, but it undergoes magical changes every day, forming wind, rain, thunder, and lightning. Do you know how these weather conditions are formed? Why do typhoons come and why can weather forecasters predict the coming of storms? When we look up at the blue sky, do you know why the sky is blue? This book - "Exploring the Weather" will give you all the answers.
Among all kinds of weather, rain is a relatively ordinary weather phenomenon, but if it is acid rain, how is acid rain formed? So why does acid rain happen? The answer to this question is found in "Exploring the Weather".
In fact, rainwater is inherently weakly acidic. This is because water vapor dissolves carbon dioxide in the air and forms weakly acidic carbonic acid. If the air is polluted with nitrogen oxides or sulfur oxides, rainwater will become more acidic. When these oxides mix with water vapor, they form weak nitric acid and weak sulfuric acid. Acid rain can gradually destroy objects made of limestone because the acid dissolves the stone. Using vinegar and chalk, you can demonstrate this process.
You just place a piece of chalk or concrete on a metal pallet. Pour some more vinegar on the stone, but don't pour too much, as this will simulate acid rain on the limestone. At that time, a "hissing" sound began to appear on the head, indicating that the stone was being dissolved! This process releases a foam of carbon dioxide, the same foam found in sparkling drinks. You can hear the hissing, but you need a magnifying glass to see the foam! Unless your vinegar is very acidic.
Alas! In fact, acid rain can also be fatal. Acid rain that falls in northern regions such as Canada, Norway, and Sweden poses the greatest danger. Winds blow acid there from nearby industrial countries. In some areas where acid rain occurs, the rocks are very hard and contain no lime at all. The acid reacted with the lime and became harmless, but because the rocks there contained no lime, acid rain flowed into rivers and lakes, poisoning all the fish. In many parts of Northern Europe, large tracts of forest are dying. This may be caused by the damage caused by acid rain, or it may be that the air and rain in your area are polluted by other factors. It seems that we need to protect the environment!
