Base

Base (chemistry) In the Brensted- Lowry classification, any chemical species, ionic or molecular, capable of accepting or receiving a proton {hydrogen ion) from another substance. The other substance acts as an acid in giving up the proton. A substance may act as a base, then, only in the presence of an acid. The greater the ten­dency to accept a proton, the stronger the base. The hydroxyl ion acts…

Any compound having highly basic properties, strong acrid taste, and ability to neutralize acids. Aqueous solutions of alkalies are high in hydroxyl ions, have a pH above 7, and turn litmus paper from red to blue. Caustic alkalies include sodium hydroxide (caustic soda), the sixth-largest-volume chemical produced in the United States, and potassium hydroxide. They are extremely destructive to human tissue; external burns should be washed with large amounts…

Alcohol

A member of a class of organic compounds composed of carbon, hydro­gen, and oxygen. They can be considered as hydroxyl derivatives of hydrocarbons produced by the replacement of one or more hydrogens by one or more hydroxyl (R-OH) groups.

Classification. Alcohols may be mono-, di-, tri-, or polyhydric, depending upon the number of hydroxyl groups they possess. They are classified as primary (RCH2OH), secondary (R2CHOH), or tertiary (R3COH),…
