In this experiment, students add ammonia to a solution of copper (II) sulfate, observe the colour changes taking place, and then reverse the reaction by the addition of sulfuric acid. The experiment is best carried out by students working …
Transition metal complexes and ligand exchange
Try this lesson plan for 16–18 year olds to support your students to research transition metal complexes, including shape, naming, bonding and ligand exchange.
Ligand Exchange
Ligand exchange (or ligand substitution) is when one ligand in a complex is replaced by another; Ligand exchange forms a new complex that is more stable than the original one; The ligands in the original complex can be …
Transition elements and complex compounds …
Colour change = ligand exchange and change in oxidation state. For the cobalt nitrate solution, Co(NO 3) 2.6H 2 O, the addition of one drop of ammonia acts as a base to remove hydrogen ions from the hexaaqua cobalt(II) ion, [Co(H 2 O) …
substitution in complex ions
A ligand exchange reaction is exactly what it says - a reaction in which one ligand in a complex ion is replaced by a different one. The following examples are taken from UK A' level syllabuses. Replacing water with chloride ions. …
Ligand exchange method for determination of mole ratios of …
Ligand exchange method is introduced as an alternative to Job’s and mole ratio methods for studying the stoichiometry of relatively weak metal complexes in solutions. The …
Ligand Substitution Experiments
Ligand Substitution Experiments. The factors that affect the colour formed for different transition metal ion solutions are: type of ligand. change in oxidation state. co-ordination number. These …
