Acid rain is a term used in many different ways. Precise term is a acid deposition and has two parts which is wet and dry.
Wet deposition refers to rain, acid, fog and snow.
PH in chemistry is a measure of acidity of solution. Pure water has a pH close that’s 7.0 at 25 Celsius (77 Fahrenheit). Nitrogen, Sulphur and carbon are the chemicals that make the rain acidic.
Cars and other places tend to mix up with the water vapor.
The rain drops become acidic in nature. Do you know how to measure acidity of rain? You can measure the acidity by using pH paper indicators that change color. Here are the instructions to measure rain, First, When its forecast to rain, place the beaker outside and collect about 5 ml of the rain water. Then, detach a strip of the hydrogen pH paper. Next, Hold one end of the pH paper strip, put the other end into the rain and take it out after one or two seconds. The part of the paper that was in the water should change color. Finally, compare the color of the paper with the scale primed on the pH paper.
The pH range is between 5.5 and .5. The pH cannot be 7 because of carbon acid rain contains rain droplets that comes from the atmosphere.
The pH can become very low when there is a big amount of acid. A lot of fish have died in ponds because the amount of acid rain is 4.9 .
