An yellow color, from sodium
Orangish yellow
Both sodium oxide and sodium chloride contain sodium ions which exhibit a characteristic yellow color when burned. This color comes from the emission of energy as the electrons in the sodium ions transition to lower energy levels. Thus, both compounds burn with a yellow flame.
Sodium Chloride, common table salt, will not burn.
Crystals of pure sodium chloride are colorless.
The color remain unchanged for pure sodium chloride.
The yellow color of the flame is due only to sodium.
If you think to color pure sodium chloride crystals are transparent.
Sodium chloride solution is neutral.
Sodium chloride doesn't burn.
Pure sodium chloride will burn and create a pure orange flame. If there are impurities present, you would see flickers or inconsistancies in the solid orange flame. Note, use a platinum wire to hold sample while burning, as a wooden split can cause these flickers if it starts to burn
Sodium chloride is colorless; any color is due to impurities.
Yes. To burn a compound you need a halogen with a higher energy than the one in the salt. So if you put sodium chloride in a fluorine rich environment and apply a flame it will burn.
