The cobalt glass blocks distracting and common yellow fire, it serves as an optical filter in flame tests, to filter the yellow flame cause by contamination of sodium

Why sodium give a flame test?
Its electrons are excited to a higher energy state in the flame, and then they immediately release that energy, which is visible as yellow light.
Why is visible light given off when a salt such as sodium chloride is exposed to a flame?
excited electrons returning to the ground state.
What color flame test does cobalt and chromium give?
putek!
What is the flame color of sodium nitrate solution?
Sodium ions will glow yellow in the presence of a flame.
What color does cobalt burn?
Imagine a sparkler... Cobalt Chloride sends off millions of tiny, yellow sparks that shoot upward with the flame. Do not get to close when doing a flame test
What color flame test does sodium give through cobalt glass?
None.
What is the purpose of using the cobalt glass in the observation of sodium and potassium?
It is appreciated for its attractive color and is also used as an optical filter in flame tests to filter out the yellow flame caused by the contamination of sodium, and expand the ability to see violet and blue hues, under fluorescent light, the cobalt glass has twice the effect. -http://wikipedia.com
How can viewing flame through cobalt glass make it easier to analyze the ions being tested in a flame test?
no Yes it does; the blue cobalt glass filters out the yellow of the sodium to make the metal ion easier to see.
Why sodium give a flame test?
Its electrons are excited to a higher energy state in the flame, and then they immediately release that energy, which is visible as yellow light.
What color flame test does Potassium give with a cobalt glass?
The color given off from the potassium through the blue cobalt glass is somewhat if a lavender, lilac color.
Why is visible light given off when a salt such as sodium chloride is exposed to a flame?
excited electrons returning to the ground state.
What would be observed if the flame tests were viewed through a spectroscope?
Emission spectrum of the elements placed in the flame. The flame test is usually applied when Sodium, Potassium or other such metals are thought to be present since they give a very noticeable result - Sodium gives orange colour to the flame (as it does to sodium street lighting!) - Potassium gives a lilac colour etc
Why does sodium chloride produces a yellow flame when heated?
Sodium burns mostly in the centre of the visible spectrum because of the way its electrons and energy levels are arranged; this corresponds to yellow.
What is the flame color of the compound sodium chloride when heated?
No, sodium chloride is a very stable compound
Which confirmatory test is for sodium?
Its Flame Test:it gives golden yellow colour to non luminous flame which is not seen through a blue glass.
What color does sodium hydroxide burn in a flame test?
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
What color flame test does cobalt and chromium give?
putek!
