It's from the French: pouvoir hydrogen (literally, the Power of Hydrogen).
This is a pH indicator.
If you're asking what a person's pH is (blood), its about 7.4. For most mammals, its 7.4. There are certain respiratory and metabolic disorders that can change the pH. If the pH is higher than 7.4, the condition is called alkalosis. If a person's pH is lower than 7.4, its called acidosis.
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
Solutions with pH below 7 are called acidic or 'acid'
It is called a neutral substance. It is not acid or base. It is neutral between them.
a pH of 7 is neutral.
Anything with a PH below 7 is an acid.
pH is measured in units called "pH" which stands for "potential of hydrogen."

A pH of seven is called neutral. E.g Water

This is a pH indicator.
Among aqueous solutions at 25C, those with a pH value below 7.0 are called "acids", those with a pH value of 7.0 are called "neutral", and those with a pH value greater than 7.0 are called "alkalis" or "bases".

The measurement of acidity is called pH. It is a scale that measures the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating lower acidity.
