The cause is the sodium emission line at 589,3 nm.
Sodium chloride does not produce a flame when heated. It simply melts into a liquid state and eventually vaporizes.
In a flame, sodium chloride produces a bright orange-yellow colour.
Sodium chloride does not produce a yellow flame when heated because it is a compound made up of sodium and chloride ions, neither of which emit a yellow flame when heated individually. A yellow flame is typically produced by the presence of sodium ions, as in sodium-based compounds like sodium bicarbonate or sodium nitrate.
No, sodium chloride is a very stable compound
Sodium chloride does not impart a distinct color to a flame test. When sodium chloride is subjected to a flame test, it typically results in a bright yellow flame due to the presence of sodium ions, rather than the chloride ions.
Sodium chloride (NaCl) typically produces a bright yellow flame when burned, due to the presence of sodium in the compound.
Sodium compounds, such as sodium nitrate or sodium chloride, are commonly used to produce a yellow color in fireworks. When these compounds are ignited, they emit a bright yellow flame.
Sodium chloride (NaCl) does not have a characteristic color when exposed to a flame test. Sodium compounds are usually identified by the strong yellow color they produce in a flame test due to the sodium ion.
Strong yellow
It is recommended to use the sodium chloride solution; the color in the flame test is yellow.
