What is the color of the flame of copper chloride?
bright green color
Copper(II) chloride imparts a bright green color to a flame. A bright green color is imparted to the flame by copper(II) chloride.
Does copper chloride burn blue?
Finally, there’s one more way to color your flames blue: Just spread copper chloride all over your fire. Use about a pound of copper chloride on a campfire that’s 3-5 feet in diameter. The fire will immediately turn blue, and will continue to burn that way for 5-15 minutes.
What color does copper make in fire?
bluish-green
The characteristic bluish-green color of the flame is due to the copper.
What color flame does chlorine produce?
blue
Low dissociation energy of copper compounds causes presence of free copper atoms in the flame, weakly emitting in green (lines between 325–522 nm). In presence of chlorine, CuCl is formed, emitting strongly in blue.
Why does copper chloride burn green?
This is because when the metal copper is burned, it makes bluish-green light. If an atom’s electrons lose energy, they drop down to a lower energy level, and the lost energy can be released as light.
Why does copper give off a blue-green flame when burned?
This is because when the metal copper is burned, it makes bluish-green light. Different types of atoms, or elements, have different gaps between their energy levels, which causes them to make light of different colors when they’re burned and lose that energy.
What color does chlorine burn?
A pretty color when ammonium perchlorate is used as oxidizer. Not too strong effect. With chlorine donors yields green color, without chlorine burns white.

What is chloride in flame test?
Chlorine atoms do not emit energy in the visible region. In the flame test, electrons in both the metal atoms and the chlorine atoms are excited to higher energy levels. These electrons emit energy of characteristic wavelengths when they return to the ground state.
Does copper burn green?
A typical flame will burn yellow-orange with a little bit of blue near the base of the wick. This is because when the metal copper is burned, it makes bluish-green light. If an atom’s electrons lose energy, they drop down to a lower energy level, and the lost energy can be released as light.
