Formation of a stable salt

Crystalline salts can be added to solutions to precipitate other salts as a result, for example, of the formation of a stable salt pair. This behaviour is encountered when two solutes, AX and BY, usually without a common ion, react in solution and undergo a double decomposition (metathesis) ... 

A less common counter ion for the formation of a stable salt of S-adenosylme-thionine is 1,4-butanedisulfonic acid. Because the pharmacokinetic properties of this compoimd in animals were not known, Moro et al. [277] developed an analytical method for this acid in physiological fluids. The authors used an lonPac...
