In chemistry, pH is a numeric scale used to specify the acidity or basicity of an
aqueous solution. It is roughly the negative of the logarithm to base 10 of the ...
The pH scale measures how acidic or basic a substance is. The pH scale ranges
from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 ...
In order to deal with these large numbers more easily, scientists use a logarithmic
scale, the pH scale. Each one-unit change in the pH scale corresponds to a ...

Scientists have come up with the pH scale for determining the concentration of
acid in a solution so we can distinguish between solutions with varying acidity.
The concentration of hydrogen ions is commonly expressed in terms of the pH
scale. Low pH corresponds to high hydrogen ion concentration and vice versa.
Definition of pH scale: A measure of acidity or alkalinity of water soluble
substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1
to 14, ...
