[Co(NH₃)₆](NO₃)₃

The reactants need not be highly soluble for metathesis reactions to take place. For example barium thiocyanate forms when boiling a slurry of copper(I) thiocyanate and barium hydroxide in water:
: + 2 -> + 2CuOH

Mechanisms

The mechanism of silver-based salt metathesis reactions are revealed with the use of , which
