pH scale
pH scale is used to measure acidity and basicity of a solution. It determines the strength of acids and bases. pH scale is a universal indicator that shows different colours at different concentration of hydrogen ions. The value of pH scale ranges from 0-14, this is a standard value taken to measure the pH of various compounds where 0 means strong acid, 14 means strong basic, and 7 means the solution is neutral. The values on pH scale is the logarithmic value of concentration of hydrogen ion.
Nature of a Solution
The nature of a solution can be defined by checking its pH value, the solution can either be basic, acidic or neutral. To check the nature of a solution we have to take a negative logarithmic value of concentration of hydrogen ion in the solution. Following are the possibilities:
- If pH < 7, solution is acidic, the acidity decreases with decrease in value hence pH=0 is the strong acid.
- If ph = 7, the solution is neutral (i.e. neither basic nor acidic).
- If pH > 7, solution is basic, the basicity decreases with increase in value hence pH=14 is the strong base.
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.
