Aluminium oxide (alumina) is amphoteric: it dissolves in both bases and acids. Classification 4. According to the Septuagint, it was the second of the fourth row, and third of the fourth according to the Vulgate. The names aluminium and aluminum are derived from the word alumine, an obsolete term for alumina, a naturally occurring oxide of aluminium. Its name comes from the fact that early investigators isolated oxalic acid from flowering plants of the genus Oxalis, commonly known as wood-sorrels.It occurs naturally in many foods. The hydroxyaluminate or hydrated aluminate can be precipitated and then calcined to produce anhydrous aluminates. The rocks are mostly pale colored, grey or pink, and in general appearance they are not unlike granites, but dark green varieties are also known.
