7- neutral (edit: water is only pH 7 or neutral when it has been distilled)
In chemistry, the pH scale is used to determine the acidity or basicity of a solution. The pH of water varies on the chemicals contained within it. Rain usually has an acidity of around 5.5 (so it is very slightly corrosive). You can also get acid rain through pollution.

What is the pH scale of lake water?
Most natural lake waters range from PH=6 to 9
How does the pH of a substance affect our environment?
The pH of a substance thrown in the environment can lead to a degradation of soils and waters.
What is the pH of spring water?
The pH of sparkling mineral water is 6.2 which means it is slightly acidic.
What should be the pH value of bottled mineral water?
Carbonated mineral waters are acidic.
What changes the pH of water making it harmful for living things?
Absorption of carbon dioxide from the atmosphere modify the pH of waters; also the pollution from human activities.
What are some household item that have a 7.0-7.9 as pH?

How does acid precipition form?
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"
Why distilled water pH is not get stable?
Distilled waters pH is not perfectly stable because it still contains ions in it. Distilled water reacts with air and will gain a pH. The CO2 in air dissolves in water, freeing ions and lowering the pH to around 5. Boiling the water can be used to remove the carbon dioxide to restore the pH to 7.
Are problems in lakes caused by acid rain solved by adding metal?
Alkaline substances (some are metals) to neutralise the waters pH.
