Distilled water is classified as a compound. It has gone through a purification process in order to remove impurities, so all that remains are oxygen and hydrogen molecules hydrogen bonded together forming little H2O molecules :)

A substance with a pH of 7 is?
Pure water or an extremely weak base or acid has a pH close to 7.
Distilled water is about the only completely neutral solution. What is its pH?
Almost anything - its not buffered. (Your first statement is false)
Why is distilled water neutral?
The number of hydroxyl ions and hydrogen ions in pure water is balanced; but a perfect neutral distilled water (pH=7,000) is only hypothetical because water absorb carbon dioxide from the atmosphere and the pH decrease under 7.
What is circumneutral pH?
Pure water has a neutral PH. as it contains the same amount of negative and positive Ions. By pure water I mean distilled water, not tap water, which contains extra ions like chloride
What is the approximate pH in distilled water?
pH electrodes will NOT give accurate pH values in distilled or deionized water. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. The readings will drift and be essentially meaningless. pH buffers are the best solutions in which to test your pH electrodes. Tap water usually has enough ions present to allow a pH electrode to function properly. Because of this, tap water is a good short term (~24 hours) solution for storage. Also, keep in mind that water (distilled, deionized, or tap) is NOT "pure" (i.e., pH equal to 7). The moment it comes in contact with air, CO2 gas begins dissolving into it, forming carbonic acid. The actual pH, therefore, will often be slightly less than 7. If you need to accurately measure the pH of a very pure sample of water, the ionic strength of the water can be adjusted without changing the pH of the water
What is pH for distilled water?
the pH of distilled water is 7.0 and is the same as pure water The solution is acidic.
Can rainwater have a pH of 7?
Pure water (distilled and non-aerated) would have a pH value of 7.0
Why distilled H2O is alkaline?
It shouldn't be. Distilled water is pure, non-isotonic water. It should have a pH of 7, neutral.
Distilled water has a hydronium ion concentration of 1What is the pH of distilled water?
pure water is slightly acidic because of dissolved carbon dioxide
Is CO neutral compound?
pure water (distilled) is neutral , It's Ph= 7
A substance with a pH of 7 is?
Pure water or an extremely weak base or acid has a pH close to 7.
What is distilled water on a pH scale?
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).
What is the pH of distilled water?
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.
Distilled water is about the only completely neutral solution. What is its pH?
Almost anything - its not buffered. (Your first statement is false)
If distilled water has a hydronium ion concentration of 1x10-7M what is the pH of a distilled water?
Distilled water has a pH of 7. It's neutral.
Why is distilled water neutral?
The number of hydroxyl ions and hydrogen ions in pure water is balanced; but a perfect neutral distilled water (pH=7,000) is only hypothetical because water absorb carbon dioxide from the atmosphere and the pH decrease under 7.
What is circumneutral pH?
Pure water has a neutral PH. as it contains the same amount of negative and positive Ions. By pure water I mean distilled water, not tap water, which contains extra ions like chloride
