The hydrated oxide is insoluble in nitric acid, but dissolves in a concentrated ] solution to give potassium hexahydroxoantimonate(V), or KSb(OH)<sub>6</sub>.<ref name="Handbook">{{cite book
⚫ When heated at 700°C the yellow hydrated pentoxide converts to an anhydrous white solid with a formula Sb<sub>2</sub>O<sub>13</sub> containing both Sb(III) and Sb(V). Heating at 900°C produces a white insoluble powder of Sb<sub>2</sub>O<sub>4</sub> of both α and β forms. The β form consists of Sb(V) in octahedral interstices and pyramidal Sb(III) O<sub>4</sub> units. In these compounds, Sb(V) atom is octahedrally coordinated to six –OH groups.
