I think its because of the salt or of the chemicals in the sea water...
This is a chemical change.
Acid rain most likely.
Clean rain has a ph of 5.6, while the ph of acid rain is 4.2-4.4.
the normal pH of rain water is about 5.6
acid rain pH 4.2 - 4.4
A "normal" rain is considered to have a pH of 5,7. But the pH of acid rains can be as low as 2. The pH of rain is very variable on the Earth and during the year.
normal rain- 5.6 acid rain- 3 to 4
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
The highest ever recording was 4.9 i think in EuropeAnswer:Normal rain has a pH of 5.5 to 4.5. Acid rain has pH of anything less than 4.5 and reaches its strongest (lowest pH) value at about a pH of 2.The highest pH for acid rain (the weakest acid rain) would be at the lower value of normal rain water.
The rain and snow that comes from the sky, does have a change on the pH value of the underground water. There is a lot of air pollution in Singapore, making the groundwater fairly acidic.Ê
Acid Rain generally has a pH of less than 5, where normal rain is about 5.6. The lower the pH value, the more acidic is the rain.
Neutral. pH below 7 is "acid rain."
