Type-I Species: soluble species that

Type-II Species: aqueous complexes that
form from the Type-I species.
·
Type-III Species: solids or other substances
with fixed activity (e.g., precipitates that never completely dissolve,
atmospheric gases, pH in a pH-controlled environment)

Type-IV Species: precipitates that could
become completely dissolved and therefore go from an activity of one to zero
·
Type-V Species: substances that could
precipitate, but do not yet exist as a precipitate
·
Type-VI Species: substances that are not
considered in the calculations
