प्रश्न

Write suitable chemical equations to show the nature of the following oxide.

Al2O3

टीपा लिहा

उत्तर

Amphoteric substances react with both acids and bases. Al2O3 reacts with both NaOH and H2SO4.

\[\ce{Al_2O_3 + 2NaOH -> NaAlO_2}\]

\[\ce{Al_2O_3 +3 H_2SO_4 -> Al_2(SO_4)_3 + 3H_2O}\]

A tetravalent element forms monoxide and dioxide with oxygen. When air is passed over heated element (1273 K), producer gas is obtained. Monoxide of the element is a powerful reducing agent and reduces ferric oxide to iron. Identify the element and write formulas of its monoxide and dioxide. Write chemical equations for the formation of producer gas and reduction of ferric oxide with the monoxide.
