| Description | To become familiar with the transfer of energy in the form of quantum, students perform flame tests, which is one way chemical engineers identify elements—by observing the color emitted when placed in a flame. After calculating and then preparing specific molarity solutions of strontium chloride, copper II chloride and potassium chloride (good practice!), students observe the distinct colors each solution produces when placed in a flame, determine the visible light wavelength, and apply that data to identify the metal in a mystery solution.

They also calculate the frequency of energy for the solutions. |
