Web10 apr. 2024 · 04/10/23 Water Online Newsletter When it comes to pH measurement in water and wastewater treatment, there are two focal points for the word ‘standard’ — one is a compliance-related state or federal water quality specifications; the other is a specific fluid used as a calibration reference point to ensure pH instrumentation accuracy. WebThe numerical value of pH is determined by the molar concentration of hydrogen ions (H+) ³. This is done by taking the negative logarithm of the H+ concentration (-log (H+)). For example, if a solution has a H+ concentration of 10 -3 M, the pH of the solution will be -log (10 -3 ), which equals 3.
