I'm sorry, but I am unable to show diagrams as I am a text-based AI. However, I can provide you with a step-by-step description of the preparation of dry hydrogen gas:
1. Fill a gas generator flask with dilute hydrochloric acid (HCl) solution.
2. Add a few pieces of zinc (Zn) metal to the flask.
3. Attach a delivery tube to the gas generator flask and connect it to a gas collection tube filled with water.
4. Heat the flask gently to start the reaction between the zinc and hydrochloric acid, which produces hydrogen gas (H2) and zinc chloride (ZnCl2).
5. The hydrogen gas will bubble through the water in the gas collection tube, displacing the water and collecting in the tube.
6. To ensure that the hydrogen gas collected is dry, pass it through a drying agent such as anhydrous calcium chloride (CaCl2) or silica gel.
7. The dry hydrogen gas can then be collected in a gas syringe or gas bag for further use.
This process results in the preparation of dry hydrogen gas.
