Webb4 mars 2024 · The flame test is an easy experiment to set up and is often conducted in science classes. The principle of the test is that the atoms of the sample evaporate and as they are hot, they give off light when present in the flame. A mixture of samples of a large amount of sample can also emit light. Why do you have to clean the Nichrome wire?
