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?
Green
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.
Do you observe halide in the upper or lower layer in a flame test?
upper layer
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).
2 Why doesn't fluorine give positive test with Belstein test?
Because in a Belstein test, the copper halide should be able to volatilize to produce green flame, an indication that a halogen is present in the compound. Copper fluoride is not volatile., hence this kind of test is not suitable for the detection of fluorine.
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.
What causes flame rollout?
insufficient secondary air
Should NEVER heat a refrigerant storage or recovery tank with an open flame because?
Because if you superheat an entrapped gas it will swell and explode.
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. )
What causes a Flame?
Rather than what the previous answer was, I believe the flame moves because of where the reaction is taking place. The combustion reaction requires oxygen as well and so where it feels an abundance of oxygen (small scale level), the reaction will follow -> which leads to the visual effect of the moving flame. Outside from that, many factors can affect motion of the flame, such as a draft from.. anything, and many more simple factors like such.
What causes a burner flame to burn at the base of the burner?
because it's hot
