noun. sehen. Theflame test is one of the most commonly used analytical processes in chemistry.It is widely used to detect and analyze the presence of certain elements in thegiven salt or compound. Cleaning the wire is achieved by dipping it in the concentrated solution of HCl (hydrochloric acid) and burning it in the hot bunsen burner flame until the wire shows no colour in the flame. 'min': 3.05, If the ion concentration is very low, then the ions are not detected by the flame test. {code: 'ad_leftslot', pubstack: { adUnitName: 'cdo_leftslot', adUnitPath: '/2863368/leftslot' }, mediaTypes: { banner: { sizes: [[120, 600], [160, 600]] } }, } } { bidder: 'ix', params: { siteId: '195466', size: [728, 90] }}, bids: [{ bidder: 'rubicon', params: { accountId: '17282', siteId: '162036', zoneId: '776156', position: 'atf' }}, ions produce different flame colours when they are heated strongly. cmpApi: 'iab', window.__tcfapi('addEventListener', 2, function(tcData, success) { var googletag = googletag || {}; { bidder: 'openx', params: { unit: '539971079', delDomain: 'idm-d.openx.net' }}, { bidder: 'ix', params: { siteId: '195451', size: [300, 50] }}, googletag.cmd.push(function() { { bidder: 'openx', params: { unit: '539971079', delDomain: 'idm-d.openx.net' }}, The clean wire is either dipped into the powder or in the ionic metal salt solution, then the wire is heated in the bunsen burner flame.
