How to Generate Nitrogen Gas

Glassware Preparation

• 1

  Set up a stand for the Erlenmeyer flask or bulb directly above a heat source.

• 2

  Add reagents to the glassware and cover with a stopper. Connect a condenser and glass tubing to the top of the stopper. Connect the condenser to a water source.

• 3

  Attach glass tubing to a closed collection container.

Decomposition of Ammonium Nitrite

• 4

  Combine ammonium chloride (NH4Cl) and sodium nitrate (NaNO2) in an Erlenmeyer flask or bulb. Add water to dissolve the chemicals if they are solid.

• 5

  Close the flask with a stopper. Ensure the system is closed tightly with tubing and a condenser attached to the top of the stopper.

• 6

  Begin running water through the condenser. Apply heat to the system.

• 7

  Wait as nitrogen gas forms above the water in the collection container.

Reverse Haber Process

• 8

  Add Ammonia (NH3) to the Erlenmeyer flask.

• 9

  Close the flask with a stopper connected to glass tubing and a condenser.

• 10

  Apply heat to the system and wait for nitrogen gas (N2) and hydrogen gas (H2) to form in the collection system.
