its neutral so the number would be 7

Pure water has a natural Ph due to the rate of dissociation to H+ and OH- is equal to rate of association to form H2O. Pure water has no free ions.
The average pH level of water is around 7, which is considered neutral. However, water pH can vary depending on factors such as location, pollution, and natural sources.
I think you are speaking about 'normal' or 'neutral' pH. This would correspond to a value of 7.0 on the pH scale and is generally associated with pure water. Check this for more details: http://en.wikipedia.org/wiki/PH
Decomposing animal matter acts as a buffer in natural water by helping to maintain the water's pH within a stable range. This natural buffering capacity helps prevent drastic changes in pH that could harm aquatic life.
The pH refers to the acidity or alkalinity of water. Therefore, your question is not directly answerable. However, if natural gas is released to the atmosphere, the nitrogen, carbon dioxide and sulfur dioxide can combine with water to form nitric acid, carboxyl acid and sulfurous and sulfuric acids, so the acidity of water with these compounds would be acidic. I can not tell you how acidic the water would be as it would depend on how much of these inert compounds were in the gas, but all acids have a pH of less than 7.
The average pH level of natural water sources in Bahrain is around 7.7, which is considered slightly alkaline. However, the pH level may vary depending on specific locations, water sources, and environmental conditions.
A pH of 6.1 means it is on the acidic side, and to be precise it has a hydronium ion concentration of 7.9x10^-7 M
The pH value of pond water can vary depending on factors such as pollution and natural processes. Generally, pond water tends to be slightly acidic to neutral, with a pH range of around 6.5 to 8.5. Regular testing is recommended to monitor the pH levels in pond water.
The pH of river water is the measure of how acidic or basic the water is on a scale of 0-14. It is a measure of hydrogen ion concentration. U.S. natural water falls between 6.5 and 8.5on this scale with 7.0 being neutral. The optimum pH for river water is around 7.4. Therefore, the color of pH paper dipped in river water would be a yellowy green around the pH of 7.4.
The pH of a natural solution can vary depending on its composition. Pure water has a pH of 7, which is considered neutral. Acids have a pH below 7, while bases have a pH above 7. Natural solutions like lemon juice or vinegar may have a pH below 7, while solutions like soapy water or baking soda may have a pH above 7.
Pure water has pH 7, so still, freshly distilled water should have a pH of 7.0. However, interaction with the atmosphere allows carbon dioxide to dissolve into it, forming carbonic acid. As a result, agitating the water or allowing it to sit for a while will leave you with an aqueous solution that drifts down in pH. Because there are no natural buffers in distilled water, the pH can go down as low as 5.0.
