For pure distilled de-ionised water at 25 oC the pH = 7
When water is heated above this temperature it pH may become less. . Reason water is in equilibrium between hydrogen ion and hydroxide ion.
Heating water makes it dissociate more into its ions.
H2O H^+ + OH^-
H2O More H^+ & more OH^-
Since we are measuring the hydrogen ion concentration[H^+] and there is more of them the the pH is < 7 (more acidic).

∙ 12y agothe correct pH of water is 7. The reasoning for this is that 7 is pH neutral with pH 1 being acidic and pH 14 being alkaline. water is a Ph neutral substance which is neither acid nor alkaline

How can you measure the pH of toluene on pH paper?
dip the ph paper (0-14) in to water than dip in to the toluene .observe the colour change of ph paper after dipping in to the water .if any change it shows ph weather it is acidic or alkaline.if it remains same as water ph shown on paper.it is neutral . my question is that weather i am doing right or wrong. give me suggestion.
What is pH of ordinary water?
The pH of water is pH7
PH of salts insoluble in water?
If the salt is insoluble, any ions in water and the measured pH is the pH of water.
Why is Chlorine quickly evaporating out of pool?
There are no shortcuts. Get your Alkalinity right, then the PH. If the PH is "bouncing," your choline will spike high and low until you get the PH right. The PH will not be right until the alkalinity is right. If all that is right, you are low on stabilizer.
Does boiling water affect its pH?
Adding water will affect the pH. Adding water will shift the pH towards the neutral mark. In the case of an alkaline solution, there will be a decrease in pH.
Where would pure water be found on a pH scale?
Pure water is assumed to be pH 7, right in the middle. It is neither an acid nor a base.
What is the range of pH for river water in India?
6.5 to 8.5 is right answer

What is a substance which is almost neutral?
Right in the middle, at pH = 7, are neutral , pure water is neutral
What is the pH value of common alcoholic drinks?
The coffee is slightly acidic, a pH of approx. 5.
What is pH of ordinary water?
The pH of water is pH7
PH of salts insoluble in water?
If the salt is insoluble, any ions in water and the measured pH is the pH of water.
What is the pH and water activity in sprouts. Is it low PH AND low water activity?
low water and low ph

When KOH is added to water what does the pH of the water solution do?
The pH of water increase.

What happens to pH of water when hydrochloric acid is added to water?
the water will get more acidic. the PH will decrease meaning the pH is acidic
