Producing Hydrogen Step 12 4 5 6 7 8 9 10 11 12 Procedure Step 3 Wrap the fine copper wire all around the magnesium, making a cage to hold it, but leaving 30 mm to 50 mm at each end of the wire free for a handle.

Producing Hydrogen Step 1 2 3 4 6 7 8 9 10 11 12 Procedure Step 5 Slowly fill the graduated cylinder to the brim with water from a beaker. As you fill the cylinder, pour slowly down the side of the cylinder to minimize mixing of the water with the acid at the bottom. In this way, the liquid at the top of the cylinder is relatively pure water and the acid remains at the bottom.

Producing Hydrogen Step 1 2 3 4 5 6 8 9 10 11 12 Procedure Step 7 Bend the copper wire handle through the holes in the stopper so that the cage holding the magnesium is positioned about 10 mm below the bottom of the stopper.
Producing Hydrogen Step 1 2 3 4 5 6 3 7 9 10 11 12 2 Procedure Step 8 Insert the stopper into the graduated cylinder; the liquid in the cylinder will overflow a little. Cover the holes in the stopper with your finger. Working quickly, invert the cylinder, and immediately lower it into the large beaker so that the stopper is below the surface of the water before you remove your finger from the stopper holes.

(This equalizes the gas pressure in the cylinder with the pressure of the air in the room.) Use this image to measure and record the volume of gas in the graduated cylinder.
