Why is copper wire wrapped around magnesium? By wrapping the magnesium ribbon in a copper wire cage, you can ensure that the magne- sium will remain in the acid environment. Hydrochloric acid is in excess in the reaction so that the moles of hydrogen gas produced may be determined from the moles of magnesium that react.
Why does the chemist use copper wire to secure the magnesium ribbon in the test tube? 3. Loosely coil the magnesium ribbon.

When the experiment is set up why must the eudiometer be filled completely with water after the HCL has been added? The eudiometer tube is carefully filled completely to avoid any air space when the tube is stoppered. When the tube is inverted into a 600-mL beaker of water, the Mg strip releases bubbles of H2 gas as the acid solution diffuses downward and reacts with the Mg.
Where did the water vapor inside the eudiometer come from? As gas (hydrogen) is produced, it will displace water in the Eudiometer. This is referred to as using “downward displacement.” As the hydrogen gas is being produced, since it is displacing the water, some water vapor will also be produced. The amount of water vapor is dependent on the temperature of the water.
