This program, divided into three parts, gives several examples of reactions: potassium thiocyanate solution with iron (III) nitrate solution to explain ionic equilibrium; acid-base chemistry, using ethanoic acid as an acid, and ethanoate ion and ammonia as bases; and copper metal with silver nitrate solution to illustrate redox chemistry.

Bonding in Molecules
View Video Clip
This program considers the bonds formed when atoms share electrons (covalent bonding). The idea of filling electron shells to reach a more stable state is used to explain the formation of simple molecules such as water and methane. Shapes of molecule...(more details)
 
Bonding Between Molecules
View Video Clip
In this program, bonding is explained in terms of dipole-dipole bonding for polar molecules, and dispersion forces for both polar and nonpolar molecules. Changes of state for water are examined, and the decreased density of ice when compared with liq...(more details)
 
Ionic Bonding
View Video Clip
This program uses the idea of filling electron shells to explain the formation of cations and anions. Electrostatic forces are then used to explain lattice formation, and the relationship between properties and structure is examined. Ionic bonding is...(more details)
 
Water: A Molecular Substance
View Video Clip
Using computer-generated animations, this program clearly demonstrates the structures and changes of state in water-specifically in ice melting, in water evaporating, and in water boiling-all at the molecular level. Each demonstration scientifically ...(more details)
 
Water: Dissolving, Precipitation, and Complexation
View Video Clip
This program, divided into three parts, looks at the difference between melting and dissolving using the example of sodium chloride. The reaction of sodium chloride solution with silver nitrate exemplifies precipitation; ammonia, added to a solution ...(more details)
