WebIn the flame test lab, the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum, which one can use to identify them. For example, NaCl was highlighter yellow, Sr (NO3)2 was sun orange, CuCl2 was turquoise, LiCl ... WebNote that the light is actually two colors that are merged together in the normal view of the flame. Record both the color of the flame and the colors of the LiCl spectra. Strontium nitrate, Sr(NO 3) 2: Note the color of the plain flame on the right. Note the colors of the flame's spectrum on the left.

The test involves introducing a sample of the element or compound to a hot, non-luminous flame, and observing the color of the flame that results. The idea of the test is that sample atoms evaporate and since they are hot, they emit light when being in flame. The solvent of the solution evaporates first, leaving finely divided solid particles which move to the hottest region of the flame where gaseous atoms and ions are produced through the dissociation of molecules. Here electrons are … http://d1068036.site.myhosting.com/PS2.f/lab8_4.html
WebStrontium chloride (SrCl 2) is a salt of strontium and chloride. It is a 'typical' salt, forming neutral aqueous solutions. As with all compounds of strontium, this salt emits a bright red colour in flame, and is commonly …

If you can buy a pocket spectroscope, you will just a broad bands of color. So a flame spectrum, specially a low temperature flame, is not equal to an atomic emission spectrum. If I introduce copper into a very hot flame (>2000 Kelvin), you will not see anything, because copper atoms emit light mainly in the UV range. first robotics wilsonvilleWebFlame tests (Li, Na, K, Ba, Sr, Cu) Theory The characteristic colours given off when salts of certain metals are heated in the flame of a Bunsen burner are noted.
