Wrong: the pH in water is 0 or 1.2
Corrected:
The pH of pure water at 25 oC is 7.0.
When left in open air however it has a bit lower pH because of slightly carbon dioxide dissolution (forming weak carbonic acid).
distilled water salts
Distilled water's pH is expected to be exactly 7; however small amounts of CO2 entering the water then form H2CO3. This can lower the pH to around 5.0 - 6.0.
The lower the pH value is from 7 (distilled water), the stronger the acid, so 1 would be the strongest acid.
Anything below the pH of 7 is an acid. Distilled water is at a pH of 7 and is considered the 'middle' of the pH chart. Anything above 7 or at 7 is a base.

distilled water salts
Distilled Water is neutral - neither acidic nor alkaline as it has a pH value of 7
Distilled water's pH is expected to be exactly 7; however small amounts of CO2 entering the water then form H2CO3. This can lower the pH to around 5.0 - 6.0.
pH value of distilled water would be 5,6 and 7 as interaction with the atmosphere allows carbon dioxide to dissolve into it, forming carbonic acid. salt on its own has no ph value but , when mixed in water the ph value of common salt is 7 and it is neutral.
the pH of distilled water is 7.0 and is the same as pure water The solution is acidic.
Distilled water has a pH of 7. It's neutral.
The lower the pH value is from 7 (distilled water), the stronger the acid, so 1 would be the strongest acid.
Pure water (distilled and non-aerated) would have a pH value of 7.0
Distilled water, if it is truly distilled to purity, has a pH of 7. This means that the concentration of hydrogen ions dissociated from the water is 1x10-7 mol dm-3. Often, distilled water is impure, and is slightly more acidic (it has a slightly lower pH than seven).
the distilled water
Anything below the pH of 7 is an acid. Distilled water is at a pH of 7 and is considered the 'middle' of the pH chart. Anything above 7 or at 7 is a base.
