Question

Осуществите превращение оксид алюминия ->нитрат алюминия -> гидрооксид алюминия->алюминат натрия Для реакций протекающих в растворах составьте ионные уровнения

Answer 1

Al2O3 +6HNO3 =2Al(NO3)3 +3H2O
Al(NO3)3 + 3NaOH =Al(OH)3 +3NaNO3
Al(+3)+3NO3(-)+3Na(+)+3OH(-)=Al(OH)3 +3Na(+)+3NO3(-)
Al(+3) +3OH(-) =Al(OH)3
Al(OH)3+NaOH =NaAlO2 + 2H2O

Answer 2

Transformation of Aluminum Oxide to Sodium Aluminate

To transform aluminum oxide into sodium aluminate through a series of reactions in solutions, we need to consider the ionization of each compound and the subsequent reactions. Let's break down the transformation step by step.

1. Ionization of Aluminum Oxide (Al2O3): - Aluminum oxide ionizes in water to form aluminum ions and oxide ions. - The ionization equation for aluminum oxide is: ``` Al2O3(s) → 2Al^3+(aq) + 3O^2-(aq) ```

2. Formation of Aluminum Nitrate (Al(NO3)3): - Aluminum ions from the ionization of aluminum oxide react with nitrate ions to form aluminum nitrate. - The ionization equation for aluminum nitrate formation is not available in the provided search results.

3. Formation of Aluminum Hydroxide (Al(OH)3): - Aluminum ions from aluminum nitrate react with hydroxide ions to form aluminum hydroxide. - The ionization equation for aluminum hydroxide formation is not available in the provided search results.

4. Formation of Sodium Aluminate (NaAlO2): - Aluminum hydroxide reacts with sodium hydroxide to form sodium aluminate. - The ionization equation for sodium aluminate formation is not available in the provided search results.

Unfortunately, the specific ionization equations for the formation of aluminum nitrate, aluminum hydroxide, and sodium aluminate are not available in the provided search results. If you have access to additional information or specific chemical reactions, I can help you further with the ionization equations.
