Why did all sodium compounds show the same colour in the flame? (flame test)

Chemistry
1 answer:
mojhsa [17]2 years ago
5 0

Answer:

Every element has its own particular spectrum of colours that the atoms or ions will emit when energy (in this case heat) is supplied. ... So, the sodium in sodium chloride, sodium nitrate, etc all produce the same bright yellow colour that is a characteristic of sodium.

Arrange the colors of visible light, green, red, and blue, in order of increasing wavelength.
lukranit [14]

Answer: The increasing wavelength of colors:

Red > Green > Blue

Explanation:

Wavelength: This is the property of wave which includes the distance between two consecutive crests or trough. This is denoted by the Greek letter Lambda and it is found by dividing the velocity of the wave with its frequency.

Wavelength of colours are

Violet: 400 - 420 nm

Indigo: 420 - 440 nm

Blue: 440 - 490 nm

Green: 490 - 570 nm

Yellow: 570 - 585 nm

Orange: 585 - 620 nm

Red: 620 - 780 nm

Leona [35]

Answer:

See the explanation below, please.

Explanation:

In the bunsen burner, the gas and air inlet can be regulated manually. In the case of metals (such as lithium and sodium in this case) they contain an electron in the latter in its external electronic configuration. They are characterized by transferring electrons easily and produce the emission of light when excited, producing flames of different colors in the lighter (orange for sodium and red / scarlet for lithium)
