A pH of 4
the pH of normal rain is said to be between 5.5 an 5. the pH is not 7 because carbonic acid is contained withing rain droplets from the atmosphere. this is how the atmosphere rids itself of toxins. pH of rain can also become very low when large amount of acid are present (from pollutants) the pH at which fish die in ponds when affected by acid rain is 4.9.

Ph 4 and under and/or pH 8 and over -because Ph7 is the normal Ph level that humans should only take.
yes, their is natural acid in your stomoch to disolve your food, but it does depend on the type of acid. Pyro2012: ACID is a term given to Another substance with a high pH level. Another answer is: No,if you think about ACID RAIN, is caused by dangerous chemicals emitted from factories,mainly Sulfuric acid. The pollution in respect to ACID RAIN lowers the pH(it tells you how acidic the substance is, in this case its the rain) levels are ,and the pollution lowers the pH level of the rain. Knowledge: High pH level= Low Acidity level Neutral pH(around 7)=neutral lol Low pH level= High acidity level
The average PH level is between 4.17 and 4.94
The pH level of acid rain is typically below 5.6, which is the pH of normal rainwater. Acid rain forms when sulfur dioxide and nitrogen oxides mix with water vapor in the atmosphere, creating sulfuric acid and nitric acid.
Any level below 5.5 or 5.4 can taint water and plants causing them to be harmful to wildlife.
The normal pH of blood is 7,35-7,45.
4.8
acid precipitation can form by air pollution, burning of fossil fuels, and Natural Resources.acid precipitation is formed from the ph level in waters. if the ph level is high and gets evaporated it will rain down as "acid rain"
It depends on where you are. If your water comes from aquifers that are in limestone rock and you are near an industrial are it is likely the faucet water will be slightly higher pH than the rain water.
it becomes more acidic
No, adding salt to water does not change its pH level to become more alkaline. Salt does not directly affect the pH level of water.
