Flame tests | Causes of Color

The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C). The orange, yellow, and red colors in a flame do not relate only to color temperature.

Colored fire - Wikipedia

Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam. When additional chemicals are added to the fuel burning, their atomic emission spectra can affect the frequencies of visible light radiation emitted - in other words, the flame appears in a different color dependent upon the chemical additives.

titrations: one at pH=10 and using Eriochrome Black T (the sum of moles of both metals is obtained) and second, at pH=12 and using Murexide (only calcium is titrated). Important: the change of indior’s color is gradual. So, the titration has to be carried to total change of color, using overtitrated sample as the color reference.

Color of chemicals - Wikipedia

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths.This spectral perspective was first noted in atomic spectroscopy.

Flame colours are produced from the movement of the electrons in the metal ions present in the compounds. (i) Calcium gives brick red colour. (ii) Strontium gives crimson colour. (iii) Barium gives apple green colour.

Calcium ion Reactions [MarZ Chemistry]

(s) Solid precipitate forming a colour change in soultion One type of reaction is not enough, to confirm the presence of aluminium, since other metal salts give the same results. For Example with NaOH, many metals give a white ppt., and hence one can''t say that the formation of a white ppt of an unknown sample with NaOH is 100% due to Aluminium ions.

Metal Flame Emission | Protocol

This emitted wavelength, or color of light, is specific to the atom present and is used to identify a metal sample in the metal flame emission test. In the metal flame emission test, we apply a metal sample to a hot flame and observe the color of the emitted light. For example, barium will emit a yellowish-green color in the flame, while copper

Calcium salts burn orange. Salts are made up of a metal and a nonmetal. In each case, it is the metal that provides the color when the salt is burned. That is why both copper chloride and copper sulfate burn blue. Other metallic salts produce some outstanding colors but can be hard to obtain. Salts of strontium and lithium burn red, while barium compounds burn green.
