Salts
The soluble salts in Western Colorado soils are sodium, calcium, magnesium,
and potassium (cations; + charged ions), in combination with bicarbonates,
chlorides and sulfates (anions; - charged ions). When dissolved in water these
compounds dissociate (separate) into their respective cations and anions. For
example, calcium sulfate (gypsum) dissociates into calcium cations and sulfate
anions.
