प्रश्न
Give the test that is used to detect borate radicals is qualitative analysis.
उत्तर
- Borax when heated with ethyl alcohol and concentrated H2SO4, produces volatile vapours of triethyl borate, which burns with green edged flame.
- \[\ce{\underset{Borax}{Na2B4O7} + \underset{(conc.)}{H2SO4} + 5H2O ->[\Delta]\underset{Sodium sulphate}{Na2SO4} + \underset{Orthoboric acid}{4H3BO3}}\]
- \[\ce{\underset{Orthoboric acid}{H3BO3} + \underset{Ethyl alcohol}{3C2H5OH}->\underset{Triethyl borate}{B(OC2H5)3} + 3H2O}\]
- The above reaction is used as a test for the detection and removal of borate radical \[\ce{(BO^3-_3)}\] in qualitative analysis.
