Antimony V -oxide

Antimony(V) oxide can be prepared by treating antimony with concentrated nitric acid. It is an oxidising agent and when gently heated loses oxygen to form the trioxide. (The change in oxidation state stability shown by antimony should be noted since it corresponds to increasing metallic character.)... [Pg.237]

The + 5 acid is known in solution and antimonates(V) can be obtained by dissolving antimony(V) oxide in alkalis. These salts contain the hexahydroxoantimonate(V) ion, [Sb(OH)(,] . [Pg.248]

Properties of Antimony(V) Oxide. Put a little antimony(V) oxide into two test tubes and test its reaction with a 10% sodium hydroxide solution and with concentrated hydrochloric acid. What do you... [Pg.275]

Preparation of Antimony(V) Oxide. Treat 0.25 g of powdered metallic antimony with 2-3 ml of concentrated nitric acid in a porcelain howl while heating it in a water hath. Consider oxidation to he completed if a sample of the obtained white powder dissolved in an alkali will not reduce an ammonia solution of silver. When oxidation is completed, dilute the reaction mixture with water and separate the precipitate by decantation. Dry the precipitate in a water bath until it is dry, and then in a sand bath (275 °C). What is observed when it is treated with concentrated hydrochloric acid and a sodium hydroxide solution Write the equations of the reactions. How can antimony(lll) oxide be prepared ... [Pg.277]

Antimony(V) oxide may be made by reacting Sb203 with O2 at high temperatures and pressures. It crystallizes with a lattice structure in which the Sb atoms are octahedrally sited with respect to six O atoms. Bismuth(V) oxide is poorly characterized, and its formation requires the action of strong oxidants (e.g. alkaline hypochlorite) on Bi203. [Pg.419]

Antimony(V) oxide has been used in solar energy applications and can be prepared from SbCls and water by a CVD spraying method [83]. [Pg.376]
