In 1909 S.P.L. Sorenson, a Danish biochemist designed a scale, known as pH, to represent the H + ion concentrations of aqueous solutions.
In this article, we are sharing the List of PH values with you. Which is very important from the perspective of all competitive exams. If you are also preparing for competitive exams, then you must study the list given below.
The pH value of any solution is a number that simply represents the acidity and basicity of the solution. The pH value of any solution is numerically equal to the logarithm of the inverse of the hydrogen ion (H +) concentration. Therefore, the pH solution is known as the negative logarithm of the hydrogen ion.
