Document Summary

Experiment #1: determination of the composition of an alloy. Since the dawn of humanity, metal alloys have often been mysteries; their composition was usually unknown. One of the first naturally-occurring alloy discovered by man was meteoric iron (a mixture of nickel and iron). This iron meteorite was used for many things, including tools, weapons, and even jewelry. Although man has been using this alloy for thousands of years, its composition was not discovered until the mid-1900s. When an alloy, or any metal for that matter, reacts with an acid, hydrogen gas is formed as a product. The amount of hydrogen formed is directly relative to the initial amount of alloy. This is known as stoichiometry; the relation between reactants and their products, which in this case is the initial metal or alloy, and the hydrogen gas produced. For the first part of the experiment, magnesium (a metal) was reacted with hydrochloric (an acid).
