pH is aquantitative measure of the acidity or basicity of an aqueous solution. It refers to the negative logarithm of H+ion concentration. The term pH is derived from the German word "potenz" which means "power," and H is derived from the chemical symbol of hydrogen. So, pH stands for ...
1. Definition of pH: - pH is a scale used to measure the acidity or alkalinity of a solution. It quantifies the concentration of hydrogen ions (H⁺) present in the solution. - The formula for pH is given by: pH=−log(H+) - The pH scale typically ranges from 0 to 14. 2....
