WebbpH. An expression, widely used in medicine, of the acidity or alkalinity of a solution. pH is the logarithm to the base 10 of the concentration of free hydrogen ions in moles per litre, expressed as a positive number. The pH scale ranges from 0 to 14. Neutrality is 7. WebbA reading that doesn’t account for the presence of these other ionic forms is meaningless at high pH because it would grossly understate the total H2S loading of the fluid when the pH drops.
