Depending on the metal in the chloride (Na, Ca, Sr, Li, ....).
When Magnesium chloride is burnt in a Bunsen flame, it imparts no colour in the flame.
No color. When burning chlorine, the flame gains no additional color from the chlorine. Examples of this may be found by burning Aluminum chloride or Magnesium chloride, both of which burn colorless. This means that Chlorine contributes no color to the flame.
A lila color, from potassium spectral lines.
A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.
Hydrogen chloride gas is colorless.
Bluish-green
When Magnesium chloride is burnt in a Bunsen flame, it imparts no colour in the flame.
Orangish yellow
No color. When burning chlorine, the flame gains no additional color from the chlorine. Examples of this may be found by burning Aluminum chloride or Magnesium chloride, both of which burn colorless. This means that Chlorine contributes no color to the flame.
Calcium Chloride burns a deep orange with a slightly lighter orange core and has a light red glow at the top. The colour calcium chloride burns is described as brick red.
The color is due to the radiation emitted by copper.
An yellow color, from sodium
The flame test for strontium - a strong red color.
A lila color, from potassium spectral lines.
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.
When flame tested, Sodium ions range from a yellow to a bright orange flame and Potassium ions give a lilac or light purple flame. Neither the Sulphate nor the Chloride ions should have emission spectra in the visible range.
Sodium Chloride, common table salt, will not burn.
