This is why I asked if a buffer is *necessary*, I don't want to change anything, and I don't want to 'neutralise' anything, I just want to take a measurement *as is*.
I'm content now, knowing that a buffer is not a requirement if simply wanting to take a straight measurement of water or a solution. Why do you add the reagent Harold? Correct me if I'm wrong, but buffers are for the purpose of increasing or decreasing acidity/alkalinity as a compensatory measure to create a neutral pH are they not? I don't wish to alter or neutralise anything, just get a reading of pH of the water/solution as it is from scratch. N. From: har...@telus.net To: silver-list@eskimo.com Subject: CS>Testing pH?
