Abstract

 

The purpose of this lab is to determine how a reaction between an unknown metal and an acid can be used to identify the metal. The acid to be used in this lab is HCl and it will react with the unknown metal in an Erlenmeyer flask while in a water bath. When they react, hydrogen gas is released into the closed container. Since the volume of the container and the temperature are both known, the ideal gas law can be used to determine the amount of hydrogen that was released. Once the number of moles of hydrogen is determined, one can calculate the three atomic weight of hydrogen using the given stoichiometric ratios. By using the periodic table, the atomic weight, and the physical properties, one conclude what the identity of the unknown metal is. It is crucial to compare the properties of the metal used in the experiment with the one identified on the periodic table to make sure they are the same to confirm the identity.
