because of various oxides [most likely SO2 SO3 and NO2].
Oxides are gas, which makes a reaction SO3 + H2O -> H2SO4 [which is sulfate acid]
Well it is similar with other oxides.
Then acid dissociates into ions H+ and SO4 2-.
And H+ ions makes a pH be lower.
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.You have to use logic if water is 7 then rain water will be higher or lower so the is 6.5
The more acidic of two acidic solutions has more H+ ions per liter.
The average pH of rainwater is around 5.6, making it slightly acidic. This acidity is primarily due to the presence of carbon dioxide in the atmosphere, which forms carbonic acid when dissolved in rainwater. A pH of 7 is considered neutral, so a pH below 7 indicates acidity.
A pH value below 7 indicates that a solution is acidic. The lower the pH value, the more acidic the solution is. Typically, acidic solutions have a pH between 0 and 6.9.
The lower the pH value is from 7 (distilled water), the stronger the acid, so 1 would be the strongest acid.

The pH value of unpolluted rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere.
The more acidic of two acidic solutions has more H+ ions per liter.
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.
Rainwater typically has a pH value around 5.5 to 6.0, making it slightly acidic due to the absorption of carbon dioxide from the atmosphere, which forms carbonic acid. On the pH scale, which ranges from 0 (very acidic) to 14 (very basic), rainwater would fall closer to the acidic side. However, in areas with significant pollution, rainwater can be even more acidic, sometimes dropping below pH 5.
Any acidic compound; one that contains an acidic hydrogen atom.
The average pH of rainwater is around 5.6, making it slightly acidic. This acidity is primarily due to the presence of carbon dioxide in the atmosphere, which forms carbonic acid when dissolved in rainwater. A pH of 7 is considered neutral, so a pH below 7 indicates acidity.
A pH value below 7 indicates that a solution is acidic. The lower the pH value, the more acidic the solution is. Typically, acidic solutions have a pH between 0 and 6.9.
The pH value of rainwater in Singapore is usually slightly acidic due to the presence of atmospheric pollutants. However, Singapore has implemented measures to reduce air pollution, leading to less acidic rainwater in recent years. The overall impact on the pH value of water is minimal.
The lower the pH value is from 7 (distilled water), the stronger the acid, so 1 would be the strongest acid.
Normal clean rain has a pH value of between 5 and 5.5, which is slightly acidic
Anything with a pH of 7 or lower is acidic, and anything with a pH of 7 or higher is alkaline.
