When you burn lithium chloride, or any other lithium salt, you get a crimson flame, due to the positive lithium ions.
The heat from burning the substance excites the outer electrons of the lithium ions to higher energy levels, when they drop back to the ground state, energy is released as light, and the wavelength of that light corresponding to that drop is crimson, hence we see a crimson flame.
Ferric chloride burns with a blue/green flame.
The flame test for strontium - a strong red color.
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.
This is not chemical: when heated in a bunsen flame it does not 'burn', it is ionised in stead, hence emitting the red light spectral lines belonging to lithium ions. It is the same behavior of sodium salt when powdered in a gas flame, though the last effect is much more 'powerfull' yellow.
When magnesium chloride is burned, it produces a white flame. This is due to the high energy levels of the burning magnesium that emits visible light in the form of white light.
Ferric chloride burns with a blue/green flame.
When Magnesium chloride is burnt in a Bunsen flame, it imparts no colour in the flame.
The flame test for strontium - a strong red color.
A pink color from the spectral lines of lithium.
Red
NaCl will burn with a brick-red colour in a non-luminous Bunsen flame.
Depending on the metal in the chloride (Na, Ca, Sr, Li, ....).
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.
You get and orange - yellow colour.
red
blue
Burning copper chloride produces a green flame due to the presence of copper ions in the compound. The green color is a result of specific energy transitions within the copper ions when they are heated.
