WebSeveral elements like gold, silver, platinum and palladium do not produce characteristic colour during the flame test. Limitations of the Flame Test 1. If the ion concentration is very low, then the ions are not detected by the flame test. 2. The light intensity varies from one sample to another. WebIf Pb, Sb, Bi, Sn or As may be present in the mixture then flame test must not be performed because they form alloy with Pt and spoil the wire. Golden yellow colour of Na exists for long time and so other flame tests must be performed after removing Na. Nichrome wire may also be used in place of Pt but results are not good.
