[LESS INFO] 10 VIEWS | ADDED 06:32:50 01/15/09
This chemistry video podcast looks at electrostatic forces and how they are responsible for holding solids together. All four fundamental forces (ie strong, weak, gravitational and electrostatic) are considered. "Mindocular' is a fictional character who has a 'minds eye' with excellent magnification and resolution and can 'see' individual particles in matter, and determine their behaviour. He looks at metallic, ionic and covalent solids.

This chemistry video podcast investigates the reactions of ethanol, 1-butanol (ie butan-1-ol), 2-butanol (ie butan-2-ol) and methyl-2-propanol (ie methylpropan-2-ol) with potassium dichromate, potassium permanganate and sodium metal. We see that tertiary alcohols are less reactive than secondary alcohols, which are less reactive than primary alcohols.

[LESS INFO] 4 VIEWS | ADDED 11:35:42 08/11/08
The pairs of electrons that exist in the valence shells of atoms repel each other as far as possible. This repulsion helps determine the shapes of molecules formed in covalent compounds. This chemistry video podcast shows some of these possible shapes and explains their formation. (Some of you have experienced difficulties with the audio on the previous version of this episode. I have re-recorded the soundtrack in this podcast. Let me know if this solves the problem. Richard)

reactions of hydroxide and ammonia solutions with salts of metals - (video) june 9 2008

[LESS INFO] 3 VIEWS | ADDED 11:07:50 06/08/08
This chemistry video podcast looks at the reactions of basic solutions (ie ammonia solution and hydroxide solutions) with solutions of metal salts (ie Mg, Al, FeII, FeIII, Cu, Zn, Ag, and Cr). As well as displaying the appearance of the resulting products, the chemical equations representing the reactions are shown. Demonstrated are the production of the complex ions aluminate, zincate and chromate from addition of excess hydroxide to solutions of the amphoteric metal salts of Al, Zn and Cr. The complex ions produced by addition of excess ammonia with Cu, Zn and Ag are also demonstrated.

It has been a long time since my last post, holidays and theft of my laptops have conspired against me. I intend to post some episodes of fundamental chemistry principles this year to help those of you in preliminary chemistry courses, or to be used for revision for others. This video chemistry podcast looks at how ionic compounds form, and how we write formulae to represent the relative amounts of ions in ionic compounds.
