Cupric sulfate produces a blue-green flame color when burned.
When a zinc solution is burned, a blue-green flame color is typically observed. This flame color is due to the presence of zinc in the solution, which emits specific wavelengths of light when heated.
Cupric nitrate typically produces a blue-green flame when burned.
The flame of barium nitrate typically produces a pale green color when burned. This green color is a characteristic flame test color for barium compounds.
Gold does not produce a flame color when burned. When heated, gold will melt and form a shiny, metallic liquid.
The flame color of cesium is typically described as a sky-blue or violet color. When cesium is burned, the electrons in the cesium atoms get excited and emit energy in the form of light, producing the characteristic flame color.
Neon does not emit a specific color when burned in a flame test. Neon gas is typically used in signs and lighting to produce a bright red-orange glow when electrically charged, but it does not exhibit distinct colors when burned in a flame.
Sprinkling charcoal powder into a non-luminous flame will not change the color of the flame. The flame color is determined by the elements present in the fuel being burned, not by adding additional substances like charcoal.
Lithium chloride (LiCl) does not emit colored flames when burned. It is commonly used in flame tests as it does not produce a significant color.
Hydrochloric acid itself does not produce a distinct flame color when burned. However, some metal chlorides formed from the reaction of hydrochloric acid with metals can produce colored flames when burned.
The yellow color is from the incandescence of not burned soot particles.
Green and is used with fireworks.
