When a strontium compound is heated in a flame, red …

2016/4/12· See below. The color of the flame is due to the light emitted by certain salts. The atoms of element contained in the salt are excited to higher energy levels due to heat of the flame. Thereafter, the excited atoms return to the ground state emitting electromagnetic radiation of characteristic frequency. This radiation is seen by the viewer as emitted color. The energy DeltaE of the emitted

How Flame Test Colors Are Produced

2020/2/21· A metal salt consists of a component ion (the metal) and an anion. The anion can affect the result of the flame test. For example, a copper(II) compound with a non-halide produces a green flame, while a copper(II) halide yields a blue-green flame.

Sodium polyanethol sulfonate | Article about sodium …

Substances containing sodium impart a characteristic yellow color to a flame. Because of its activity sodium is not found uncoined in nature. It occurs abundantly and widely distributed in its compounds, which are present in rocks and soil, in the oceans, in salt lakes, in mineral waters, and in deposits in various parts of the world.
