Limitations of pH scale
pH scale has the following limitations:
- pH scale is not useful for very strong acids and bases outside the range of 1-14.
- The relative strength of the solutions is not given by the pH scale
- At higher concentrations of strong acidic solutions (i.e. 2N, 3N, 5N, etc.,) the pH values will be negative.
- Hammett acidity functions are used instead of the pH scale when solutions are at higher concentrations.
pH of Acid and Base
pH stands for Potential of Hydrogen, which simply means the power of hydrogen in a compound. pH value helps determine the nature of the solution. It helps to define the acidity and basicity of a solution. pH value should be balanced for the proper well-being of the environment and living organisms.
This article will cover information about the pH of acid and base, the pH scale, the calculation of pH value and the importance of pH.
