The test has difficulty detecting small concentrations of some elements, while too strong a result may be produced for certain others, which tends to cause fainter colors to not appear. To conduct a flame test: Clean a platinum or nichrome wire with acid. Primarily, the flame test detects the presence of metalions in a compound, and as ions of each element have a specific characteristicbased in their emission spectrum, the flame test for every element is differentand distinctive. To carry out a flame test: dip a clean wire loop into a solid sample of the compound being tested put the loop into the edge of the blue flame from a Bunsen burner observe and record the flame colour produced The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. The objectives of this lab are to: a) Perform flame tests of metal cations in order to observe their characteristic colors, b) Match the flame colors observed to an appropriate wavelength of visible light, and then perform calculations to determine the frequency and energy of the emitted photons, c) Relate these results to the types of electronic transitions occurring in these elements, d) Practice writing … To relate these results to the types of electronic transitions occurring in these elements. The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. Thisdistinction is shown by the color of flames given out when the salt containingcertain me… In this lab, you will perform flame tests of several different metal cations. Moisten the wire with water. Dip the wire into the solid you're testing, making sue that a sample sticks to the wire. The characteristic colors observed are due to emitted electromagnetic radiation from the excited metal cations. In … However, the range of elements positively detectable under these conditions is small, as the test relies on the subjective experience of the experimenter rather than any objective measurements. Circle the correct responses to complete the following statement: EM radiation is emitted when electrons make transitions from low / high to low / high energy levels. In this lab, how do the metal cations become "excited"? The flame test is relatively quick and simple to perform and can be carried out with the basic equipment found in most chemistry laboratories. Place the wire in the flame and observe any change in the flame color. Theflame test is one of the most commonly used analytical processes in chemistry.It is widely used to detect and analyze the presence of certain elements in thegiven salt or compound.
