Complex Ions Reversible ligand substitution with copper chloride
Hydrated copper (II) chloride is dissolved in water and concentrated hydrochloric acid is added to change the colour of the solution from blue to green-yellow. The ligand substitution is then reversed by adding an excess of deionised water. The structures of the complexes and the thermodynamic and equilibrium factors are discussed briefly.
Esters 6. Alkaline hydrolysis of esters (inc. saponification)
This short video looks at the alkaline catalysed hydrolysis of both simple and complex esters - the later making a soap in what is also known as a saponification reaction. The hydrolysis of ethyl ethanoate is shown first, followed by the hydrolysis (saponification) of tristearine. The next video in the series looks at how we determine the saponification value of a fat or oil.
