I think it is around 7 because it doesn't harm anything. It I either that or doesn't have a pH

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.
How does Ph regulate breathing?
It doesn't. pH is a measure of acidity or alkalinity of a substance, breathing is taking oxygen out of air and putting out carbon dioxide.
What happens by passing a current of atmospheric air on pure water of ph 7?
When you pass a current of atmospheric air on pure water of PH 7, the specific heat index of water will increase.
Why the pH of fresh groundwater slightly decrease upon exposure to air?
oxygen form air is dissolved in water
What are the disadvantages of Ph paper?
Some disadvantages of using pH paper is when the pH paper is exposed to air for too long it collects other molecules in the air and when a solution is put on top of the paper it mixes with the other molecules creating a new solution, throwing off the measurements and ruining the experiment.
Why the pH of groundwater slightly decrease upon exposure to air?
when the groundwater is exposed to the air the carbondioxide present in the air gets dissolved in the water due to which the ph of groundwater decreases

Why is the pH of deionized H2O often less than 7.0?
Because when it is exposed to air, the CO2 will effectively lower the pH

Does an apple turn brown in the air because of pH solution?
no, its oxidation
What happens to the pH level in fruit juice when exposed to air?
It should riseIt will not occur directly, but once exposed to air the water will begin to evaporate concentrating the juice and thereby increasing the pH level
Why the pH of fresh groundwater slightly decrease upon exposure to air?
oxygen form air is dissolved in water
Does pollution affect pH balance?
AIr polution does affect pH in the oceans so it would in pools as wel to a very small extent.
Which outcome would you expect if you measured the pH of area of high air pollution?
The rainwater would be acidic with a pH less than 5.6.

What is discrepancy between the calculated pH and the experimental pH of the buffer solution?
Air. Carbon dioxide from the atmosphere enters the aqueous solution and forms carbonic acid, which increases the concentration of hydronium, thus lowering the pH.
