Acid Rain....

Posted Monday, January 24, 2011 by Jinting
Acid rain is very harmful to the environment. Acid rain affects the life in the water as well as the life on land. It is almost worse in water than on land because the fish and aquatic plant that are survive in the water need the water for respiration. Acid rain also leaves a lot of aluminum in the soil, which can be harmful to the trees that grow in forest. The acid rain dissolve waxy protective coating of leaves, damaging them and preventing them from being able to photosynthesise properly.

Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this...As, it is never acidic enough to burn your skin. Normal rainwater has a pH of 5.6. When the pH level of rainwater goes below 5.6, it is considered acid rain.

How to reduce the damage caused by acid rain? Lakes and rivers can have powdered limestone added to them to neutralise the water - this is called "liming". Liming, however, is expensive and its effects are only temporary - it needs to be continued until the acid rain stops.
