In chemistry, pH is used to gauge the acidity or basicity of an aqueous solution. It stands for "Potential of Hydrogen" and is defined as the negative logarithm of the hydrogen ion (H⁺) concentration. The pH scale values extend from 0 to 14 , with a value of seven considered neutral. 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 . pH is a scale used to measure the acidity or basicity of a solution. It ranges from 0 to 14 and reflects the relative concentration of hydrogen ions (H⁺) and hydroxide ions (OH⁻) in aqueous solutions. To calculate pH , take the log of the hydrogen ion concentration and change the sign of the answer. In chemistry, pH is a number that describes the acidity or basicity (alkalinity) of an aqueous solution. The pH scale normally runs from 0 to 14. A pH value of 7 is neutral. This is the pH of pure water. Values less than 7 are acidic, while those greater than 7 basic. Here is a quick review of how to calculate pH . It includes formulas for finding pH and examples showing how to use them. pH ...
