Title: Species Distribution Diagrams in the Copper -- Ammonia System: An Updated and Expanded Demonstration Illustrating Complex Equilibria.
Authors: Johnson, Adam R., McQueen, Tyrel M., Rodolfa, Kit T.
Source: Journal of Chemical Education. Mar2005, Vol. 82 Issue 3, p408-414. 7p.
Subjects: CHEMICAL reactions, CHEMICAL equilibrium, COMPLEX ions, ACID-base chemistry, SOLUBILITY, ALGEBRA, EQUATIONS
Abstract: The article discusses species distribution diagrams in the Copper-Ammonia System. This seemingly simple system encompasses three major classes of equilibrium chemistry commonly taught in inorganic chemistry, which are acid-base, complex ion formation and solubility. The updated demonstration emphasizes the fact that coupled equilibria, while complicated and difficult to solve exactly, can be readily understood and explained by simple algebraic equations. It is also a useful summative demonstration that could end an entire unit on chemical equilibria. Selected portions of this demonstration have been used successfully at both the introductory and advanced undergraduate level.
