2. Most salts contain a metal and a non-metal. Look at the compounds you tested and determine whether it is the metal ion or the non-metal ion that is responsible for the color produced in the flame test for that salt. How can you be sure your answer is correct? -The metal ion is responsible for the color of light because in all of the compounds, either nitrite of chloride is used yet the

What causes different colors in flames?
What causes different colors in flames? Asked by: Jimmy Willard Answer Colors in general result from either emission of light of specific wavelengths, or absorption of light of specific wavelengths from a mix of photons. At the root of both emission and absorption is
Oxidizing and reducing flames - Wikipedia
In various burners, the oxidizing flame is the flame produced with an excessive amount of oxygen.When the amount of oxygen increases, the flame shortens, its color darkens, and it hisses and roars. With some exceptions (e.g., platinum soldering in jewelry), the oxidizing flame is usually undesirable for welding and soldering, since, as its name suggests, it oxidizes the metal''s surface.
