Acids and bases are important to many chemical processes: maintaining a stable internal environment in the human body, baking a delicious cake, or determining whether a lake can support aquatic life. Reactions involving acids and bases can be described through the transfer of protons. The reactions of acids and bases, which can be monitored with indicators, can range from corrosive behavior to neutralizations that leave no acids or bases behind. To understand the controlling of pH of solutions, buffers are discussed in the laboratory and in the chemistry of the bloodstream. Part of Chemistry: Challenges and Solutions Series.

Explores space stations, lunar bases, and Mars landings as possible solutions to earth's environmental and overpopulation problems. Questions cover both positive and negative aspects of this ambitious, speculative future.
Part of the "Chemistry in Action" series. Demonstrates how chemical compounds are placed into groups so that they may be studied easier. Explores acids and bases, emphasizing their nature and common everyday uses. Discusses carbon compounds, and introduces the following terminology: acid, base, pH, salt, carbon, organic, and hydrocarbon.
Why is RNA just as cool as DNA? Join the Amoeba Sisters as they compare and contrast RNA with DNA. Part of "The Amoeba Sisters" series.
This series explores the relationship between humans and the sea and focuses on the life of the sea turtle. Turtles worldwide face serious threats of extinction; however, conservation efforts are trying to preserve this species. Part of the "Turtle World" series.
Cosmetics are big business. They are used by almost every person walking on the Earth. Shows how cosmetics are made and how they have been used for thousands of years. Outlines bases, bulking agents, coloring agents, fragrances, and preservatives. Demonstrates the making of an emulsion and explains the processes of distillation or solvent extraction.
Sherlock Olmos decides to dig deeper into dark corner of this great house to investigate the suspicious behavior of some chemical elements. The exchange of electrons and the characteristics of hydrogen, fluorine gas, and the noble gases are the primary subjects of his investigation. Part of Chemistry: Solved by Sherlock Olmos Series.
In the early 1950s, American biologist James Watson and British physicist Francis Crick came up with their famous model of the DNA double helix. The structure of DNA, as represented in Watson and Crick's model, is a double-stranded helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together. Other topics covered include DNA replication, RNA transcription, and RNA translation. Part of the "Biology" series.
