Heat and Mass Transfer
pH is a measure of the acidity or alkalinity of a solution, expressed on a logarithmic scale ranging from 0 to 14, where 7 is neutral. The pH scale indicates the concentration of hydrogen ions in a solution; lower pH values correspond to higher acidity, while higher values indicate alkalinity. Understanding pH is crucial in processes such as adsorption and ion exchange, as it can significantly influence the behavior of ions and molecules in various solutions.
