In chemistry, pH is a numeric scale used to specify the acidity or basicity of an
aqueous solution. It is approximately the negative of the logarithm to base 10 of ...
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 ...
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 ...
Switch between logarithmic and linear scales. Investigate whether changing the
volume or diluting with water affects the pH. Or you can design your own liquid!
Jul 9, 2015 ... The pH scale is something we're all familiar with; most people will remember it
from school chemistry lessons. It's the scale used to rank how ...

Develop. To define the pH scale as a measure of acidity of a solution ...
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.
Oct 17, 2015 ... pH stands for power of hydrogen, which is a measurement of the hydrogen ion
concentration in the body. The total pH scale ranges from 1 to 14 ...
The pH scale was defined because the enormous range of hydrogen ion
concentrations found in aqueous solutions make using H<sup>+</sup> molarity awkward.
In this educational animated movie about Science learn about acids, bases,
basic, alkaline, neutral, ions, buffers, and neutralization.
