Impacts can be classified under three headings.
1.Impact to animals
Acid rain impacts us without our being aware of it.
You may have the misconception that acid rain causes little damage.
Acid rain damage actually does impact us!
Metal such as copper in acid rain is eaten by plankton.
That plankton is eaten by a little fish, and that a little fish is eaten by a big fish.
That big fish is eaten by us.
It is said biological concentration, chemical is condensation for food chain.
We are impact of acid rain for biological concentration.
Be able to preserve one´s survival like some of insect, plankton and waterweed ware resistant to acid.
If it collapses, the ecosystem will be beyond repair.
2.Impact to plants
You may be aware of this, because one often hears of it in the news.
One famous impact is the withered plant residue in the Black Forest in Germany.
Similar phenomenon occurring in many parts of the world.
Air pollutants in the city have been falling along with the rain
3.Impact to buildings
It sometimes happens that acid rain dissolves concrete buildings.
Acids have ability to dissolve calcium carbonate
Carbonates of calcium.
It is reactive with strong acid to form carbon dioxide..
Which means that
Thus carbonate is dissolved and gets hard again on contact with the CO2 in the atmosphere
Concrete icicles are formed in this manner.
Chemical equation ： CaCO3 + 2H^+ →Ca^2+ + H2O + CO2
