Copy. because the electron jumps made in lithium chloride give out a reddish color when moved to the excited state of the visible light spectrum. the heating moves them up to the ... WebTranscribed image text: Consider NaCl, LiCl and LiBr. Select all true statements. LiCl and LiBr will have the same flame color because they both contain Li ions. NaCl and LiCl will have different flame tests because they don't contain the same metal cation. NaCl and LiCl will have the same flame test color because they both contain Clions.

Solved Consider NaCl, LiCl and LiBr. Select all true - Chegg
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 ... WebLithium chloride imparts a red color to a flame. A carmine-red color is imparted to the flame by lithium chloride. The color is less intense than the strontium flame color. A few tinges of yellow-orange sodium color appear as a consequence of traces of sodium impurity in the lithium chloride solution. WebFlame Test Lab Analysis Analysis: 1.
