Why is yellow color is imparted to the flame when glass is heated?
the bright yellowish orange tells you that there are sodium coumpounds used in making the glass. it is so intense, that it hides the flame color givenoff by Ca+2 & by K+ it needs to be heated to energize the electrons of sodium much like you energize water when you boil it into steam ... i found that on yahoo answers :D -margo
What is the colour of sodium and potassium flame through a cobalt glass?
The flame color of sodium through a cobalt glass appears yellow, while the flame color of potassium through a cobalt glass appears lilac or pale violet. The cobalt glass filters out certain colors, allowing specific wavelengths to pass through, which affects the observed flame color.
What is the purpose of using the cobalt glass in the identification of potassium and sodium?
Cobalt glass filters out yellow light, allowing only violet and blue light to pass through. Sodium produces a bright yellow flame color that is masked by cobalt glass, while potassium produces a light purple flame color that is visible through the cobalt glass. This technique helps distinguish between the two elements based on the flame color observed.
Why glass rods are used for flame tests in inorganic qualitative analysis?
Glass rods are used in flame tests for inorganic qualitative analysis because they are inert and do not react with the chemicals being tested. This ensures that the observed flame color is only due to the metal ions present in the sample. Additionally, glass rods are transparent, allowing for better observation of the flame color.
Why is the sodium flame is not visible through the cobalt glass?
The cobalt glass absorbs specific wavelengths of light, including those emitted by the sodium flame. This absorption of light by the cobalt glass results in the sodium flame not being visible when viewed through it.

What type of property is exhibited when when glass tubing is heated over the flame?
because of co 2
What happen if a flask is heated on a flame with a wire gauze?
Heating a flask on a flame with a wire gauze helps distribute the heat evenly and prevents direct contact between the flame and the glass, minimizing the risk of the glass breaking. The wire gauze also helps to spread the heat more uniformly, reducing the chances of hot spots developing in the glass.
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.
Does glass looked different when heated opposed to glass not heated?
Yes, because if glass is heated it breaks, if glass is not heated it doesn't break.
Does glass heated in a hot flame glow and becomes fluid?
Glass can soften and become pliable when heated in a hot flame, but it does not glow like metal does when it reaches high temperatures. It does not become fully fluid like a liquid, but it can become molten and flow like a thick syrup.
What does glass smell like when it is heated?
When glass is heated, it does not have a distinct smell.
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
