Flame tests can be used to identify some metal ions (cations). WebJan 25, 2024 · The flame test is a diagnostic test used to identify the ions, mostly cations in an ionic compound. The cationic part of an ionic compound is the metal part; hence the flame test helps us identify the metals present in an ionic compound.

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 ... dialysis clothing amazon https://ugscomedy.com

WebThe next job is to do your flame tests. Dip the flame test loop into one of the known test solutions, then hold the metal loop in the edge of the Bunsen burner flame. Make a note of the colour of the flame on your Flame Test Chart (a simple version is shown below). Clean the flame test wire, then test another known test solution. WebFlame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.
