Reactions

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.

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.

Rates of Reversible Reactions

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Don't make the most common mistake in Oxidation Reduction! This question confuses so many students. Watch this video to learn how to do this right. In chemistry, reduction is the gain of electrons, and oxidation is the loss. Oxidation reduction reactions are often called redox reactions for short.
