The inverse logarithm of the concentration of hydronium ions in a water solution; basicaly, how acidic a solution is.
H+
The pH scale
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.
measuresA. 0 to 14
Because if you went on solely the concentration of hydrogen ions within the solution, you would end up with numbers like 1.38x10-5. pH puts these numbers into a more user-friendly scale
The pH scale measures the acidity of a substance. It ranges from 1-14. 7 is neutral, anything below that is acid. The lower the number the more acidic the substance is. If it is higher than 7 it is alkali, which means it is a base. And the opposite of acid, the higher the number the more alkali it is.
Yes, it is true that the pH scale indicated the acidity (as well as how basic) of a solution.
Using the pH scale.
The pH scale
When referring to acidity of a solution one uses the pH scale. The lower the number, the higher the acidity. Pure water is said to be neutral, and is a 7 on the scale. Anything with a lower number ranking is acidic, and anything with a higher ranking is basic.

pH
The pH scale - pH stands for percent-Hydrogen; indicating that the scale tests the concentration of free hydrogen bonds in a known solution. The higher the concentration of hydrogen bonds, the more acidic a solution; the lower the concentration of hydrogen bonds, the more alkaline or basic a solution. The scale ranges from 0-14, with 0 being the most acidic solution and 14 being the most alkaline (basic). A pH reading of 7 is a neutral substance - it is neither acidic nor basic. The pH is the measure of the acidity or alkalinity of a solution
I am not aware of the pH of Oreos. pH is a measure of the acidity or basicity of a solution and is typically measured on a scale of 0 to 14, with 7 being neutral. Food products such as Oreos do not typically have a pH value as they are not a solution.

The Richter Scale is used to determine the earthquake density. The scale is measured from low as 1 to high as 10.
