How can the nature of a solution be defined?

The nature of a solution can be defined as acidic, basic, or neutral by examining its pH value. This involves calculating the negative logarithm of the concentration of hydrogen ions in the solution. There are 3 ways in which the nature of a solution can be defined:

• If the pH is less than 7, the nature of the solution is defined as acidic, with pH 0 indicating a strong acid. The acidity of the solution decreases as the pH increases from 0 to 7.
• If the pH is greater than 7, the nature of the solution is defined as basic with pH14 indicating a strong base. The basicity of the solution decreases as the pH decreases from 14 to 7.
• At pH 7, a solution is neither acidic nor basic. If the pH of the solution is 7, its nature is defined as neutral.
