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 instrument is used to measure a waters pH level?
This instrument is called pH-meter.
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.
Why is the pH of surface waters often higher then most ground waters?
The pH of surface waters is often higher than that of most ground waters due to the presence of carbon dioxide, organic matter, and various minerals that can lower groundwater pH. Surface waters are influenced by atmospheric interactions and photosynthetic activity, which can increase pH by removing CO2 and promoting the formation of bicarbonates. Additionally, surface waters may receive inputs from alkaline sources, such as runoff from soils rich in limestone. In contrast, groundwater can be more acidic due to longer residence times and the leaching of minerals.
Is mineral water is acidic alkaline or neutral?
Mineral water can vary in pH, but it typically falls within the neutral to slightly alkaline range. The specific pH can depend on the mineral content of the water, with alkaline mineral waters having a higher pH compared to neutral mineral waters.
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?
household ammonia has pH of approximently 11.5
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"
What is the pH of spring water?
The pH of spring water can vary depending on the specific source, but it is typically around neutral pH, which is 7.0. However, it's important to note that the pH of spring water can be influenced by factors such as the surrounding geology and presence of minerals.
Where eocean waters absorb carbon dioxide water becomes more acidic which means the pH of the water is?
Lower.
Are problems in lakes caused by acid rain solved by adding metal?
Alkaline substances (some are metals) to neutralise the waters pH.
What is pH level of bottled water?
The pH level of most bottled waters typically falls in the range of 6.5 to 8.5. This range is considered safe for drinking and generally reflects a neutral to slightly alkaline pH level. It's always advisable to check the specific bottle label for accurate pH information.
