The normal pH of rainwater is slightly acidic (around 5.6) due to the presence of carbon dioxide in the atmosphere. Carbon dioxide dissolves in rainwater to form carbonic acid, which lowers the pH of the rainwater.
Now, carbon dioxide, sulphur dioxide and nitrogen dioxide in the atmosphere dissolved in rainwater form acid rain because originally, non-metal oxides form acids when they dissloved in water.

What is the pH of normal rain water?
This will depend entirely on the area in question and atmospheric composition but usually the pH is just under neutral (7) due to dissolved Carbon Dioxide in the rain making it slightly acidic.
What is the pH of unpolluted rainwater?
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
What is the pH value of unpolluted rainwater?
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.
What is the pH of natural rainwater?
The pH of natural rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when dissolved in rainwater.
Which sectence correctly compars the acidty of natural rainwater?
Natural rainwater is typically more acidic than neutral water because it absorbs carbon dioxide from the atmosphere, forming carbonic acid. This makes rainwater slightly acidic with a pH around 5.6.

Suggest why normal rain water is slightly acidic?
Normal rainwater has a pH of 5.6 (slightly acidic). This is because it is exposed to the carbon dioxide in the atmosphere. The carbon dioxide gets dissolved in the rainwater and forms carbonic acid (H{-2}CO{-3}).
What is the pH of unpolluted rainwater?
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
Is rainwater acid or alkali or neutral?
Rainwater is slightly acidic, with an average pH of around 5.6. This slight acidity is a result of interactions with carbon dioxide in the atmosphere, forming carbonic acid.
Which gas will cause rainwater to have a pH of 6.0?
A PH of 7 is neutral, a PH falling below this means that the water is acidic. Carbon dioxide and SO2 are common gases found in the air which, when when dissolved in rainwater, will cause it to become acidic and thus lower the PH.
What is the pH level of rainwater?
The pH level of rainwater is typically around 5.6, making it slightly acidic. This acidity is due to the presence of carbon dioxide in the atmosphere, which forms carbonic acid when dissolved in rainwater.
What is the pH value of unpolluted rainwater?
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.
Why does rainwater have a much lower pH than pure water?
Rainwater can have a lower pH due to the presence of dissolved gases like carbon dioxide, which forms carbonic acid when mixed with water, leading to acidity. Additionally, rainwater can pick up acidic pollutants from the atmosphere, such as sulfur dioxide and nitrogen oxides, further lowering its pH.
What is the pH balance of rainwater?
The pH of rainwater is typically slightly acidic, with a pH around 5.6 due to the presence of carbon dioxide in the atmosphere forming carbonic acid when it dissolves in rainwater. However, the pH of rainwater can vary depending on location and atmospheric conditions.
What is the pH of natural rainwater?
The pH of natural rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when dissolved in rainwater.
What is the pH value of rainwater and why and what does it mean?
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.
What is the pH value of rainwater?
The pH value of rainwater is around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere.
