A lake that has been affected by acid rain can have a ph of 4. so the lake is 10,000 times acidic than seawater
Seawater has a pH of 8, so there's a difference of 4 pH units, so there's a difference in hydrogen ion concentration of 10^4.
- here Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average
- Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
