GCSE Chemistry Flame Tests Quiz - By Spikeypikey

WebOct 14, 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. But such light is not good for identification ... WebThe flame test is thus used to identify metal ions by the colour of the flame they produce. Dip the loop of an unreactive metal wire such as nichrome or platinum in dilute acid, and … Webaltering the colour of the flame. 2.
