Webexpressed as pH(CaCl2). Soil pH in water Distilled water is used in place of 0.01M calcium chloride, and results are expressed as pH(w). The pH(CaCl2) test is the more accurate of the two pH tests, as it reflects what the plant experiences in the soil. The values of pH(CaCl2) are normally lower than pH(w) by 0.5 to 0.9. A WebJan 24, 2016 · If you want to know how much acid you need to add to get to a pH of 6.99, it is important to take account of the fact that water is slightly dissociated. But that was not the question. The question was simply . what is the concentration of H 3 O + And that follows directly from the definition of p in pH: $$\rm{pH = -\log_{10}([H_3O^+])}$$
