Dear Upendra We had a long discussion about this in 2009. In particular, John Graybeal's posting of 25 Mar 2009 gives several different pH definitions. It appeared that these versions of pH are probably not the same geophysical quantity, and it is therefore necessary to specify which one it is. Although they all have the same general intention of measuring something like H+ concentration, they are more distinct than just being different measurement techniques. You are right, if they were all the same geophysical quantity measured in different ways, we wouldn't record the measurement technique in the standard name.
