pH is the acidity of a solution. based on amount of hydrogen (hence the H)
pH 1-6 is acidic and pH8-14 is basic
so anything less than 7 is an acid and anything above 7 is a base.
7 is neutal and would be water.

A PH measures the acicidy or alkaline of a substance. A PH scale goes from 1 - 14
A PH of one would indicate very strong acid, the higher the PH goes (before 7) the weaker the acid. At 7 the solution is neutral (water has a PH of 7) At 8 is is slightly alkaline and at 14 is is very alkaline.
So, the further away from 7 it is, the stronger the acid/ alkali

ph is a measure of the acidity of a solution
pH = -log[H+]
if
ph<7 acidic
ph=7 neutral
ph>7 alkaline

pH is the negative logarithm of hydrogen ion concentration of a solution. 7 in the pH scale means that the solution is neutral. If the value is <7 then it means that the solution is acidic, while pH being>7 means that the solution is acidic
e.g. the pH of water is 7, of blood it is 7.4 and 13 if HCl

pH tell us "How much acidic or basic a solution is?"
7 pH is the mean position which tell us that the solution is neutral
If it crosses 7 pH mark upward (towards 8) the solution will be alkaline in nature.
And if it crosses 7 pH mark downward. the solution will be acidic in nature
because
pH=-log[conc. of H+ or OH- ions]

ph: is known as hydrogen ion concentration
it is refers to the degree of acidity or alkalinity of the chemical solution and mediums of microorganisms cultures
it is calculated by numbers from 1:14 . if the number is under 7 it refers that this solution is acid.if the number more than 7 it refers that this solution is alkaline . if the number is 7 it refers to the neutralization of this solution (like water).

ph is the measure of how Acidic or Alkalinic a substance is. It is a scale from 1 to 14. Seven(7) means the substance is NEUTRAL. one (1) means it is ACIDIC whereas 14 means it is ALKALINE. You get the picture.

ph is the measure of the acidity of the matter.
if the ph is 7 then it will the neutral.if ph is more than 7 then it will be the base.

ph is potential of hydrogen.When ph crosses 7 it becomes alkaline.

it is the measure of the H+ ion concentration
or the measure of the acidity
pH=-Log[conc.H+ ions]
if the pH increases more than 7 than it turns basic
