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. 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.

WebGCSE AQA Analysing substances Flame tests and chemical tests are used to detect and identify ions in samples. Instrumental methods of analysis are faster, and more accurate and sensitive... 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. he is here adley

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 concentrated … Webwith characteristic colours. Method: dissolve a small quantity of the substance in water. place about 5cm 3 of the solution into a test tube.; add a few drops of sodium hydroxide solution. 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 he is healthy
