When using the halide torch for refrigerant leak detection a small leak causes a flame?
One "lights" the halide torch and it burns a blue flame. While the flame is burning blue, one uses a "sniffer" tube to probe for a chloroflurocarbon leak, (older style, ozone depleating refrigerant). The sniffer tube sucks in the leak and causes the flame to turn a greenish color due to the burning of the refrigerant. Thus one has now detected a leak. There are also other methods available for detecting a leak ie. soap bubbles, dyes, and electronic leak detectors.

What is colour of flame if the of Halide Torch detects a refrigerant leakage?
The flame of a Halide Torch will change to green if it detects a refrigerant leakage. This color change is due to the presence of chlorine or fluorine compounds in the refrigerant reacting with the flame. It serves as a visual indicator to alert the user to the presence of a leak.
What is the normal color of the gas flame in a halide leak detector?
The normal color of the gas flame in a halide leak detector is blue. If the flame changes to a different color, it can indicate the presence of halides in the gas being tested.
What is the color flame for Cu?
For Cu (I) and Cu(II)-as halide: blue-green color. For Cu(II)-non halide: green color.
What chemical has a green flame?
Many elements are green in a flame test: B, Tl, Te, Sb, Cu(II) (copper not in a halide).
Do you observe halide in the upper or lower layer in a flame test?
In a flame test, halides typically appear in the lower layer of the flame. Halides produce distinctive colors when exposed to a flame, such as green for chloride, blue for bromide, and purple for iodide. These colors help in identifying the presence of halides in a compound.
What is the Beilstein test in chemistry?
The Beilstein test is a simple chemical test used in chemistry as a qualitative test for halides. It was developed by Friedrich Konrad Beilstein.[1] A copper wire is cleaned and heated in a Bunsen burner flame to form a coating of copper(II) oxide. It is then dipped in the sample to be tested and once again heated in a flame. A positive test is indicated by a green flame caused by the formation of a copper halide. This test is little used nowadays; one reason why it is not popular is that it is possible to generate the highly toxic chloro-dioxins if the test material is a polychloroarene.[2] An alternative wet test for halide is the sodium fusion test - this test converts organic material to inorganic salts include the sodium halide. Addition of silver nitrate solution causes any halides to precipitate as the respective silver halide. :)
What causes the luminousity of a flame?
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
Should NEVER heat a refrigerant storage or recovery tank with an open flame because?
heating a refrigerant storage or recovery tank with an open flame can cause the tank to explode due to the high pressure of the refrigerant inside. This poses a serious safety hazard to anyone in the vicinity and can result in injury or property damage. Always use proper heating methods and equipment designed for working with refrigerants.
Principle involved in beilstein test?
The Beilstein test is based on the principle that halogens, when burned in the presence of a copper oxide flame, form a colored flame due to the formation of copper halide salts. The test is used to detect the presence of halogens, particularly chlorine, bromine, and iodine, in organic compounds. The green or blue flame color indicates the presence of a halogen.
When an air conditioner is leaking is it dangerous?
Breathing in or contacting the refrigerant (gas) is a health hazard. Some types of refrigerant-gases are highly flammable when exposed to an arc or an open flame. The question does not specify the substance that is leaking from the air conditioner.. (Is it water or gas. )
Why does blowing out a candle work to extinguish the flame?
Blowing out a candle extinguishes the flame because it disrupts the balance of oxygen needed for combustion. When you blow on the flame, you remove the oxygen surrounding the wick, which is necessary for the flame to continue burning. This sudden lack of oxygen causes the flame to go out.
What causes a burner flame to burn at the base of the burner?
because it's hot
