The ammonia acts as both a base and a ligand. Reactions of hexaaquacopper(II) ions with ammonia solution Note: You will find the reactions between hexaaqua ions and hydroxide ions discussed in detail if you follow this link. The oxygens which were originally attached to the copper are still attached in the neutral complex. Note: The colour coding is to show that this isn't a ligand exchange reaction. This is insoluble in water and a precipitate is formed. Once a hydrogen ion has been removed from two of the water molecules, you are left with a complex with no charge - a neutral complex. Hydroxide ions (from, say, sodium hydroxide solution) remove hydrogen ions from the water ligands attached to the copper ion. The reaction of hexaaquacopper(II) ions with hydroxide ions Use the BACK button on your browser to return to this page. Note: If you aren't happy about complex ions (including the way they are bonded and named), it would pay you to follow this link and explore the first couple of pages in the complex ions menu before you go on. The simplest ion that copper forms in solution is the typical blue hexaaquacopper(II) ion - 2+. The page also covers some simple copper(I) chemistry. The chemistry of copper(II) is mainly summarised from elsewhere on the site, with links available to more detailed explanations. This page looks at some aspects of copper chemistry required for UK A' level exams.
