: The cation that forms the least soluble salt (the one with the lower Kspcap K sub s p end-sub relative to its stoichiometry) will precipitate first.
open bracket cap A n i o n close bracket sub m i n end-sub equals the fraction with numerator cap K sub s p end-sub and denominator open bracket cap C a t i o n close bracket sub i n i t i a l end-sub end-fraction The cation that requires the concentration of the added anion to reach its cap K sub s p end-sub will precipitate first.
