Answer to: Why do KCl and CaCl2 produce different flame colors even though K+ and Ca2+ are isoelectric? (orange red) – color flame clearly distinguishable o Copper Chloride CuCl 2 (blue/green) – color flame clearly distinguishable o Lithium Chloride LiCl (fuchsia flame) – color flame clearly distinguishable o Potassium Chloride KCl (light lilac) – color flame distinguishable (better than any other tested) {/eq} and {eq}CaCl_2 Although {eq}KCl Why do different metals have different... Why do some elements produce colorful flames? Using known values of emmision spectra, one can perform a flame test on un unknown substance, gather an emmision spectrum from it, and determine which elements are in the unknown substance. If your sample has any sodium contamination, the color you observe may include an unexpected contribution from yellow. ZnSO4 - blue/green. Which of the following statements are true? 8 years ago . In order to return to its ground state, the electron releases the additional energy in the form of light. Figure 1 (left): Copper is heated and as the electrons fall back, certain color of light is emitted. 0 0. KCl - pink/purple. Blue flame Red flame. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Anonymous. {/eq} have isoelectronic metals, the metals have different amounts of protons so the pull on their electrons... Our experts can answer your tough homework and study questions.

CuCl2 - Blue/green. © copyright 2003-2020 Study.com. Copper chloride, also called cupric chloride, produces a blue color in a flame test. For example, in the case of copper ion, there are multiple different "paths" that the excited electrons can follow to emit photon of certain discrete energy. Get your answers by asking now. Why do KCl and CaCl2 produce different flame colors even though K+ and Ca2+ are isoelectric? Be aware, sodium yellow overwhelms other colors. If the energies are different, the light released will be of a different color. no clue help. The color is muted when sodium salts are placed in a blue flame, such as a Bunsen burner or alcohol lamp.

For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. The flame test produces various colors when testing metals because the electrons that get released have a specific energy that gets released as light. Different metal electrons emit different wavelengths of light to return to their respective ground states, so the flame colors are varied. Services, Working Scholars® Bringing Tuition-Free College to the Community. Have questions or comments? Fireworks are produced by gunpowder and chemicals... 1. These flames can be used to produce atomic emmision spectra of the elements combusted. Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. (right): Submicroscopic view of the electron movement, as electrons fall. When additional chemicals are added to the fuel burning, their atomic emission spectra can affect the frequencies of visible light radiation emitted - in other words, the flame appears in a different color dependent upon the chemical additives. Explain why a positive flame test for sodium is... Why does a salt compound give off light (or a... Why do different elements produce distinct colors... Why did different elements have similar results in... Missy Mae performs a flame test on the unknown... Why is potassium visible through cobalt glass?

Pb(NO3)2 - blue This produces multiple spectra lines because each discrete energy level difference will yield a specific wavelength of light, which determines the color. Violet flame White sparks Yellow sparks. SrCl2 - Red.
