Flame Spectrophotometric Determination of Calcium in …
Recently calcium has been found to be contained in nodular cast iron in microquantity. It is very difficult and time-consuming to determine it in such cast iron by the usual chemical methods. In this research, therefore, the flame spectrophotometric method was applied for the determination of calcium, after the separation of iron as chloride by extraction with amyl acetate or MIBK

Flame tests | Causes of Color
Flame Color tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red.
Solved: Why do we see distinct colors when metal salts …
The color obtained on burning metal salts actually depends upon the metal. When heat is provided to a material, the electrons inside the material jump to higher energy levels. As these electrons

The Flame Test Lab was an experiment designed to show how elements react when heated. This Lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element. This test showed that there is a direct coloration between the heat energy being expelled and the movement of electrons from one energy level to the next.
