Question

Как из железных опилок получить гидроксид железа (||)? Это очень срочно.

Answer 1

Так как Железо не очень реактивное чтобы при взаимодействии с водой образовывать гидроксид, то можно использовать реакцию для начала получения соли Железа, а потом подействовать раствором аммиака на эту соль.

Fe + H2SO4(разбавленная) = FeSO4 + H2

FeSO4 + 2NH3 + 2H2O = Fe(OH)2 + (NH4)2SO4

Answer 2

Объяснение:

Fe+2HCl=FeCl2+H2

FeCl2+2NaOH=Fe(OH)2+2NaCl

Answer 3

How to Obtain Iron Hydroxide (Fe(OH)2) from Iron Filings?

To obtain iron hydroxide (Fe(OH)2) from iron filings, you can follow the steps below:

1. Prepare the Materials: Gather the necessary materials, including iron filings, water, and a container for the reaction.

2. Add Water: Add water to the container. The amount of water will depend on the desired concentration of the iron hydroxide solution.

3. Add Iron Filings: Slowly add the iron filings to the water while stirring continuously. The iron filings will react with water to form iron hydroxide.

4. Observe the Reaction: As the iron filings react with water, you will notice the formation of a brownish precipitate. This precipitate is iron hydroxide.

5. Filter the Solution: Once the reaction is complete, you can filter the solution to separate the solid iron hydroxide from the liquid. Use a filter paper or a fine mesh to collect the precipitate.

6. Wash and Dry: Rinse the collected iron hydroxide with distilled water to remove any impurities. Then, allow it to dry completely.

Please note that the reaction between iron filings and water to form iron hydroxide is a simple method, but it may not yield pure iron hydroxide. The obtained product may contain impurities or other compounds. If you require pure iron hydroxide, additional purification steps may be necessary.

Keep in mind that working with chemicals and conducting experiments should be done with caution and proper safety measures. It is recommended to consult a chemistry expert or refer to reliable laboratory procedures for more precise instructions.
