The pH is a measure of the hydrogen ion (H+) activity in a solution.
pH is not a change at all. It is a chemical condition.
No, pH is a chemical property.
The PH is its acidity
pH is a chemical property :)
it is acid because a chemical is acid if pH is <7 ,base if pH>7 and neutral if pH=7
It is a chemical change.
Yes, the pH of vinegar (acetic acid) around 2.4 is a chemical property. pH is a measure of the acidity or basicity of a solution, and it is determined by the concentration of hydrogen ions present in the solution.
indicator
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
An "acid" is a chemical that has a PH lower than 7.0 and a "base" is a chemical that has a PH higher than 7.0. It would be impossible for a chemical to have a PH both lower and higher than 7.0 at the same time. Pure water has a PH of exactly 7.0 and is therefore neither an acid nor a base.
what is the chemical formula for thymol blue
The definition of a neutral chemical is an aqueous solution with a pH of 7.0 ([H+] = 1.0 x 10-7 M)
