Acids, Bases, and Neutralization
|
|
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 varying
degrees of acidity. An on-site visit to a neutralization plant in Japan
shows how acid levels are reduced by putting quantities of limestone into
the Yukawa River. A third lesson demonstrates precautions that should be
taken when performing experiments involving heat. Investigations that use
chemicals such as chlorine bleach, ether, and metallic sodium, which should
not be attempted in a school lab, are also demonstrated.
