Dihydroxialumini sodium carbonate (INN) or dihydroxyaluminum sodium carbonate (USAN) is a basic carbonate of aluminium and sodium, used as an antacid. It is prepared by the reaction of an aluminium salt with excess sodium carbonate in the presence of sodium hydroxide at pH 7.2–10.5.[1] It also occurs naturally as the mineral dawsonite.[2]
The mineral form has six-coordinate aluminium (four hydroxide ions and two trans carbonate ions) and six-coordinate sodium (four carbonate ions and two trans hydroxide ions).[3]
