Why flame color of salts is determined by metal

29/05/2017· Why flame color of salts is determined by metal. If a pure metal is heated up in a flame, we see it giving the flame a characteristic color, e.g. N a burns yellow. If a salt, e.g. N a C l or N a X 2 S O X 4, is heated up, resulting color to a greater degree still is that of the pure metal. Although the color does change depending on the anion

07/12/2016· The easiest colors to get are the longer wavelengths, such as red, orange, and yellow. Thelongest wavelengths of red have the least energy of any of the visible wavelengths, or colors. Burning. strontium chloride (SrCl2) yields red, calcium chloride (CaCl2) gives orange, and various sodiumsalts produce yellow.

01/01/1997· Carbon occurs predominantly as the isotope 12 C but there also is a small amount of 13 C; the concentration of 13 C varies slightly from 0.99 to 1.15% depending on the source of the element, the most usual value being 1.10% which leads to an atomic weight for “normal” carbon of 12.0107 (8).
