WebFlame Test. Slightly open the air hole of the Bunsen burner. Heat a piece of nichrome wire in a Bunsen flame until the flame is no longer coloured. Dip the loop at the end of the … WebA flame test is carried out by cleaning a platinum or nichrome wire by placing it in concentrated hydrochloric acid. We use platinum or nichrome because they have a high melting point (so it won’t melt in the flame) …

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 then hold it in the blue flame of a Bunsen burner until there is no colour change This cleans the wire loop and avoids contamination

WebGCSE. AQA Chemistry. 4.8 Chemical analysis. 4.8.3 Identification of ions by chemical and spectroscopic means. 4.8.3.1 Flame tests. Flame tests can be used to identify some metal ions (cations). Lithium, sodium, potassium, calcium and copper compounds produce distinctive colours in flame tests: Lithium compounds result in a crimson flame. 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.

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.
