The pH is a number which represents conventionally the hydrogen ion concentration of an aqueous solution.For practical purposes, its definition is an experimental one.The pH of a solution to be examined is related to that of a reference solution (pHs) by the following equation:in which E is ...
The International Union of Pure and Applied Chemistry (IUPAC) has a slightly different pH scale based on electrochemical measurements of a standardbuffer solution. Essentially, the definition uses the equation: pH = -log aH+ where aH+stands for hydrogen activity, which is the effective concentration...
