Boron trifluoride - Wikipedia
Boron trifluoride is the inorganic compound with the formula BF 3.This pungent colourless toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds. BF 3 Molar mass 67.82 g/mol (anhydrous) 103.837
In flame tests, salts that are dissolved in water are evaporated using a hot flame. In the flame, the metal atoms become excited and produce their characteristic spectrum of light. However, since the observer does not use a spectroscope only one color is observed.

Boron - University of Denver
2002/11/24· Boron gives a blue-green flame, and the brown amorphous form is often used in pyrotechical devices for this purpose. The color can be distinguished from the emerald green of copper. Sodium, potassium, magnesium and calcium oxides are kept to minimal amounts, since it is their exclusion that gives the glass its desirable properties.

Flame test: brick-red color originates from calcium [Wikimedia] The metal can be identified in the composition of compounds by the undissolved sediments of some salts of the element (fluoride, calcium carbonate, sulfate, silie, phosphate, sulfite)
What makes a green flame? | EveryThingWhat
The most common cause of a green flame is the presence of chemicals containing copper inside the fire. When copper is heated up (for example, by being in a hot fire) it can absorb energy in a process called “atomic excitation.” The electrons in the copper atoms
Calcium chromate - WikiMili, The Free Encyclopedia
Calcium chromate (CaCrO4) is a bright yellow solid. It normally occurs as the dihydrate, although the very rarely natural (mineral) form, known as chromatite, is anhydrous. Very toxic. Boron is a chemical element with the syol B and atomic nuer 5. Produced
Atoms - universe-review Contents
A crude and cheap method to detect metal ions is the flame test, which heats the sample on a loop of platinum wire moistened with hydrochloric acid (HCl) in a colorless flame. Figure 13-01f shows the color of the flame from sodium carbonate (Na 2 CO 3 4).
