Except for several complex species such as ammonium chloroplatinate,(NH₄) ₂PtCl₆, ammonium salts are very soluble in water.

Changes in the acidity of precipitation are reflections of changes in the balance between the major cations and anions in precipitation. Thus, to understand the acidity of precipitation, it is essential to measure all the major anions and cations in precipitation(especially H+, SO4=, NO3-, and NH4+, but also including K+, Na+, Ca+, Mg++, C1-, HCO3-, SO3=, and PO4=).  2, record 7, English, - dominant%20cation
