Summary: Until the 17th century, the building blocks of the natural world were a mystery. Of elements there were believed to be four - air, earth, fire, and water - and the science of chemistry had yet to be born. This program identifies some of the first chemical elements to be discovered by spotlighting the work of Hennig Brandt, Robert Boyle, Henry Cavendish, Joseph Priestly, Antoine Lavoisier, and...

Summary: At the beginning of the 19th century, 55 elements had been discovered, and although scientists had no idea how many more they might yet find, they already had a suspicion that there was some sort of unifying pattern behind them all. This program charts the quest for order among the chemical elements by examining the contributions of Dmitri Mendeleev, creator of the Periodic Table of Elements,...

Summary: Lesson one demonstrates the circumstances under which common materials, such as sugar and table salt, conduct electricity. The process of electrolysis is demonstrated in the making of metallic leaves. In investigating the movement of ions, permanganate ions spread toward the anode side of a liquid chamber when electricity is applied. Lesson two demonstrates the formation of a metallic copper...

Summary: In the first lesson, five aqueous solutions are tested for degrees of acidity and alkalinity. The nature of acids and bases is examined. In lesson two, table salt is produced by mixing small pieces of aluminum with solutions of hydrochloric acid and sodium hydroxide. Current flow in acid, neutral, and alkaline solutions is demonstrated. An experiment using ammonia water and dry ice tests...

Summary: In lesson one, heat is used to distill ethanol. Iodine distilled from seaweed demonstrates the chemical phenomenon of sublimation. The principle of chromatography is explored by studying color pigments in water-base pens. Lesson two studies salt dissolution. Degrees of solubility are measured by dissolving quantities of boric acid at different temperatures. Recrystallization is achieved. In...

Summary: In lesson one of this program, experiments are conducted on five white "mystery" powders to determine chemical content and reaction. Salt is fused into a solid block. By feeding gaseous oxygen into a plastic bag of liquid nitrogen, we observe the resulting changes in gases; argon condenses into liquid, then turns to gas upon being removed from liquid nitrogen. Lesson two shows the three states...

Summary: The first lesson provides examples of the Law of Conservation and Mass and the Law of Definite Proportions. Recycling of elements is examined. In lesson two, exothermic and endothermic reactions are demonstrated by an experiment that uses the chemical contents of a pocket warmer and dry ice. The third lesson includes demonstrations of oscillating reactions and clock reactions, as well as...

Summary: An explanation of the theory of infrared absorption is followed by showing a series of spectra demonstrating the major absorption peaks. Shifts within the carbonyl group, and their explanation, are discussed. The N.M.R. portion of the program covers the ideas of integration, chemical shift, and splitting in proton spectra in a logical process of development of the subject.

Summary: An explanation of how a mass spectrometer works is followed by a demonstration of a mass spectrometer in action. The analysis of simple mass spectra is discussed-simple splitting of hydrocarbons, the effect on splitting of heteroatoms in alcohols and ethers, and the McLafferty rearrangement. Discussion of the spectra of isotopic mixtures, such as chlorine and bromine, and the use of accurate...
