Electrochemistry and the Dualistic Theory
Lavoisier had defined an element as a substance so far undecomposed. His table of elements in the Traité included earths such as lime and magnesia, but he predicted that one day their compound nature would be revealed: ‘... they will fall to be considered as compounds consisting of simple substances, perhaps metallic, oxydated to a certain degree’. So sure was he that potash and soda were compounds that he omitted them from his list of elements. In 1800 a completely new way of effecting chemical decomposition became available, and with its aid Lavoisier’s predictions were verified.
