It indicates the concentration of H+ ions in an aqueous solution.
It measures the acidity or alkalinity of a liquid. A pH of 7 (green with universal indicator) denotes Neutral. Anything below that is acidic, and anything above it is alkaline or basic.
For everyday use, the pH scale goes from 1 (red) to 14 (purple).
*The pH scale measures the concentration of H+ ions (or the acidity/alkalinity) in a solution. It is found by log-1 [H+], and ranges on a scale from 1 to 14 with 1 being the most acidic solution, 14 being the most basic solution, and 7 being neutral.
The pH is a measure of how acidic or basic(alkaline) an aqueous solution is.
Pure water is neutral, with a pH = 7. Things with a pH <7 are acidic, and things with a pH >7 are basic.
The theoretical pH of an aqueous solution is defined this way:
pH = -log10 [aH+]
pH is the logarithmic measurement of the H3O+-concentration in water solutions.
By definition: pH = -log[H3O+]
Example: [H3O+] = 1.0*10-7 mol/L in neutral, pure water (at 25oC), so
pH = -log(H3O+) = -log(1.0*10-7) = 7.0
A measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. The pH scale commonly in use ranges from 0 to 14.
A substances pH level is essentially a measure of the power of hydrogen within that substance: it is a logistic representation of the number of hydrogen atoms formed in an acidic or basic substance.
pH is the concentration of H+ or in other words acid. The lower the pH is, the more acidic it is.
PH is the measure of somethings acidity or alkalinity. So just as Oranges are acidic that means their pH is acidity. To find the measure you use a pH meter. hope that helps =)
pH measure the acidity/basicity of a solution.
The acidity of a solution (apex)
acidity
an instrument which is used to measure the strenght of acid and base is called PH scale.
The pH scale measures the amount of available H+ ions. Specifically pH=-log10[H+]
The pH scale is used to measure how acidic or basic a substance is.
pH indicator, pH paper, and a pH meter. You can find them on this page http://onsager.bd.psu.edu/halmi/chem3pHS05.pdf
1-14
by using a scale
The pH scale does not measure hardness it measures the acidity or otherwise of substances
PH scale
it indicate the acid and base of the scale
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
pH is a measure of acidity/alkalinity of a solution.The classic pH scale is between 0 and 14.
Ph. stands for potential of hydrogen. The Ph. scale is used to measure the acidic level of a specific solution.
The pH scale (not hP) is used to measure the acidity/basicity of an aqueous solution. It actually is a measure of the hydronium ion concentration. pH <7 is acidic; pH>7 is basic; pH=7 is neutral.

The pH scale measures the amount of available H+ ions. Specifically pH=-log10[H+]
