Purpose: In this lab I will observe alkali and alkaline earth metal ions from performing flame tests. When a metallic ion is heated in a flame test, the heat causes an electron to be exicted to a higher energy state. When this electron returns to a lower energy state, energy is emitted as visible light. Depending on how much energy is released when the electron returns from the higher to lower energy state will determine what color the flame will be. Colors in general result from either emission of light of specific wavelengths, or absorption of light of specific wavelengths from a mix of photons. At the root of both emission and absorption is the excitement of electrons. The colors will hopefully allow me to differentiate between different alkali and alkaline earth métal ions. Procedure: Start the lab reading all of the lab seven materials. Create a safe workspace clear of debris and clutter. Lay out all of the required material including; chemicals, 24- well plate, burner, matches, q-tips, and goggles. Wear the goggles before working with any chemicals. Put .5ml of each of the nitrates into a different we of the 24-

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
