Examples

  • When Lavoisier presented his antiphlogistic system, this system proved in principle so perfect that one could confidently predict that many well-known substances, such as alkalis and alkaline earths, were not elements but oxides of hitherto unknown metals -

  • There are two types of caustics: acids alkalis (also known as bases)

    Caustics

  • Potentially serious exposures usually occur when strong alkalis or acids are used in an enclosed, poorly ventilated area for a prolonged period of time.

    Nuclear fuel cycle

  • Its legacy is tangible, with terms like algebra, algorithm and alkali all being Arabic in origin and at the very heart of modern science - there would be no modern mathematics or physics without algebra, no computers without algorithms and no chemistry without alkalis.
