of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high
number of hydrogen ions is acidic and has a low pH
value. A solution with a high
number of hydroxide ions is basic and has a high pH
value. The pH
scale ranges from 0 to 14, with a pH
of 7 being neutral.

Other than that, what determines water pH?
pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
Ergo, what makes something acidic or basic? One water molecule gains a hydrogen and therefore takes on a positive charge, while the other water molecule loses a hydrogen atom and therefore becomes negatively charged. H 3O + is called a hydronium ion, and it makes things acidic. OH - is called a hydroxyl ion and it makes things basic.
Despite everything, on what factors pH depends?
The neutral value of the pH depends on the temperature, being lower than 7 if the temperature increases. The pH value can be less than 0 for very strong acids, or greater than 14 for very strong bases.
Is 9.5 pH water good?
Drinking natural alkaline water is generally considered safe, since it contains natural minerals. However, you should use caution with artificial alkaline water, which likely contains fewer good minerals than its high pH would have you believe, and may contain contaminants.

Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That's why 7 is neutral. ... In pure water near room temperature, the concentration of H+ is about 10-7 moles/liter, which gives a pH of 7.
The general definition of the pH value of a solution is the negative base-10 log of the concentration of hydronium ion in the solution. ... While on the other end is not more than 1M of hydroxide ions which results in a pH value of not more than 14.
Reading the pH scale It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. All other substances are compared to this neutral point.
is only defined for an aqueous solution. It's a measure of the relative concentration of hydrogen and hydroxide ions in the water. A pure substance can
be defined as acidic or basic with reference to the reactions it will take part in, but it doesn't have a pH

Mostly – measured pH values will lie in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Since pH is a logarithmic scale, a difference of one pH unit is equivalent to a tenfold difference in hydrogen ion concentration.
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it's possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
How soda ash/sodium hydroxide injection works. This treatment method is used if water is acidic (low pH). Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.
A *dilution* is where the concentration of a solute is decreased by adding more solvent--typically water. Since the volume of the solution increases, the molarity decreases. Thus, for an acidic solution, the pH will increase, whereas for a basic solution, the pH will decrease.
The pH ever so slightly decreases when we boil the water, because the rate of forward ionization increases. However, this doesn't mean the water is now acidic but rather the neutral point is now slightly lower than 7. ... That means, at that higher temperature the neutral pH is not 7 but rather 6.
There has been no evidence of harm found in drinking water with a pH of between 7 and 8.5. (Interesting to note: The pH of human blood is a little on the basic side, 7.365.) When the PH of water becomes greater than 8.5, water taste can become more bitter.
But for most healthy individuals, drinking alkaline water is probably not harmful. If you have chronic kidney disease or are taking a medication that affects your kidney function, elements in alkaline water could possibly have negative side effects on the kidneys. Consult with your doctor first.
