Although often considered synonymous with base, alkalis represent a subset of bases, defined as either the group of alkaline earth metals or basic salts composed of them or more broadly any base that forms hydroxide ions when dissolved in water. The word alkali (and the adjective alkaline) comes from the Arabic word al qaliy which means the calcified ashes and referred to the products of calcination-usually the burning of lime to produce cement. Some etymological dictionaries give the Arabic qala, to roast in a pan. The English word kiln is often supposed to come from culina (kitchen) an unexplained variant of coquere, to cook. Perhaps there is a missing Proto Indo-European root to link these words for cooking and roasting.
Mono Lake, California, pictured above, is an alkali lake with an unusual ecosystem based on brine shrimp that utilizes the heavy salt concentration. The lake was briefly famous when NASA discovered an organism that is capable of metabolizing arsenic in December 2010.

The word base has been around virtually unchanged since Ancient Greece as the word basis to denote a step or pedestal. Use of the word base as a chemical term to describe the chemical reactions of acids with other materials dates from 1754 and the French chemist Guillaume-Francois Rouelle. As the science of chemistry grew, the word base was refined to mean a susbstance that can accept hydrogen ions (protons) or donate electrons. Today there are several different definitions of the word, all corresponding to accepting protons or donating electrons.
Lithium Hydroxide (pictured above) is a typical strong base with a wide variety of uses: for respirator systems in spacecraft, as a battery electrolyte, in ceramics and some cements.
This memo is to remind all SHIELD employees that when we defeat an enemy and seize their installations and equipment, no one is to vocalize in any way whatsoever the phrase “all your base are belong to us.”
