Sodium Carbonate and Aluminium - dangerous? : chemistry

Mar 13, 2008  Sodium carbonate is a weaker base, so it should be much slower at dissolving the Al2O3. But reactions generally get faster when the reagents are hot, so that is probably what it happening to your bucket. As the Al2O3 dissolves, it replaces and displaces the CO2 in the carbonate, so the CO2 also should bubble out with the H2.

Aluminum salts may cause phosphorus depletion which is generally negligible. However, with prolonged administration or large doses, hypophosphatemia may occur, especially in patients with inadequate dietary intake of phosphorus; hypercalciuria secondary to bone resorption and increased intestinal absorption of calcium results. This phosphorus depletion syndrome is characterized by anorexia ...

Sodium Aluminate AMERICAN ELEMENTS

Sodium does not occur in nature as a free element and must be extracted from its compounds (e.g., feldspars, sodalite, and rock salt). The name Sodium is thought to come from the Arabic word suda, meaning "headache" (due to sodium carbonate's headache-alleviating properties), and its elemental symbol Na comes from natrium, its Latin name.
