stability
Will not decompose if used and stored in accordance with specifications. No known hazardous reactions to avoid oxides. Insoluble in water. Almost all acids are insoluble except hydrofluoric acid. Eutectic with potassium bisulfate, or with alkali hydroxide or alkali carbonate, yields tantalate equivalents of various metals, respectively. Tantalate is generally easy to be hydrolyzed, completely decomposed by strong inorganic acid, precipitate white colloidal tantalic acid. Tantalum pentoxide is obtained when tantalum acid is completely dehydrated.
