WebA flame test is done by holding a sample of your compound on a piece of wire in a Bunsen flame. Ideally the wire is made of platinum because that doesn't itself give any colour to the flame. But normally in a school lab, you will probably be using nichrome wire - an alloy of nickel and chromium. This is much cheaper but tends to give a very ... porthcawl deathsWebGCSE AQA Analysing substances Flame tests and chemical tests are used to detect and identify ions in samples.
