Science Lab Experiment: Preparation of Hydrogen
Demonstration: Hydrogen Preparation
Object: To find out what happens when magnesium is added to vinegar.
Materials: vinegar, 2 test tubes, matches, wooden splint, magnesium ribbon
Diagram:
Method: A 5 cm piece of magnesium ribbon was added to 3 ml vinegar in one
test tube. A second test tube was placed mouth downward over the top
of the first test tube to collect the gas produced by the reaction.
After a few minutes, a lighted wooden splint was placed inside the
second test tube and observed.
Observations: When the magnesium was added to the vinegar, bubbles formed.
Steam appeared on the inside of the second tube. The lighted
wooden splint inside the second test tube caused a "pop".
Conclusions: Since a burning splint will cause hydrogen to pop, it was
concluded that the gas formed was hydrogen.
