Homework Help: Chemistry

Posted by chrisalis on Saturday, January 12, 2008 at 9:10pm.

In regards to atomic emission spectroscopy:

Explain why the intensity of the color gets brighter when the metal salt concentration is higher. Salt is any ionic compound that has positive ions(called cations) and their associated negative ions (called anions). For example, lithium nitrate is a salt as well as sodium chloride.

AND

Explain why you see a colored flame when you burn the salt solution. That is, what is going on with the salt when it's heated to give off the color light? Which part of the salt, the metal ion or its anion, gives off the color light?


I want to gather an understanding of this, but I fear that its a bit over my head. Thanks!
