St. Patrick’s Day Demonstration

In this demonstration, the gas supply for the flame contains boric acid. In general, when a substance is heated in a flame, the substance’s electrons absorb energy from the flame, are promoted to excited energy levels, and then emit light as they relax back down to the ground state. In the case of boron, the emitted light is green.

Boric Acid - The Chemical Company

Boric acid, also known as boracic acid or orthoboric acid, is a naturally occurring compound containing the elements boron, oxygen, and hydrogen (H3BO3). Boric acid crystals are white, odorless, and nearly tasteless. It looks like fine table salt in the granular form or like baby powder in the powdered form.

The Emission Spectrum from a Candle Flame (1 Favorite) - AACT

May 30, 2017· The light emitted by the carbon particles gives the flame its bright yellowish glow, but the hot particles of carbon in the candle flame actually emit light of various colors. This emission can be observed by separating the colors using a diffraction grating, as shown in this demonstration.

why does boric acid and methonal turn fire green.? | Yahoo

Jan 13, 2010· Why does boric acid and methonal turn fire green.? When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon. The wavelength (or, equivalently, frequency) of the photon is determined by the difference in energy between the two states. The fact that only certain colors appear in an
