I have measured the pH in the water-soluble fraction of a powder. I weighed in a certain amount of powder and a certain amount of water, and extracted the water-soluble fraction. I then measured the pH in this extract.
How do I report this? The pH depends on the amount of powder and the amount of water. Should I give the weighed-in amounts along with the pH-value? Or is there a way to "normalize" the pH-values to make them comparable for all? Just giving the pH values make no sense, as no one can compare anything to them.
