The Range of the pH Scale is from 0-14. The pH range for the existing solution will always lie in the range between 0 and 14. Any solution that has a pH value less than 7 indicates acidity. On the other hand, any solution that has a pH of greater than 7 will indicate a base. A pH of 7 is often labeled as a neutral solution. Water has a pH of 7; thus, it is a neutral solution.

Range of pH Scale

The pH scale is a measure of the acidity or alkalinity of a solution. There is a reason why pH outside the conventional is always in the range of 0-14. This is the only possible range for pH because they depend on various possible limitations. These limitations are caused by the instruments added to the solution and the solution itself that may restrict measuring the total pH of such substances.

In most cases, the pH range is 0-14, but in a strong acid solution, pH could be less than zero, and in highly concentrated basic solutions, pH could be more than 14. However, these are exceptional cases. The pH measures the relative amount of hydroxyl ions and free hydrogen in the water.

The pH scale is used in many scientific fields, including chemistry, biology, and environmental science, to measure the acidity or alkalinity of substances and to determine whether they are suitable for certain applications. The pH scale is also useful in the field of agriculture as the pH of the soil is an important factor that affects plant growth and crop yields.
