Vedclass · Answer

(A) The borax bead test is used to identify transition metal ions that form colored metaborates upon heating with borax $(Na_2B_4O_7 \cdot 10H_2O)$.Transition metals like $Co^{+2}$,$Cu^{+2}$,and $Ni^{+2}$ form colored beads (blue,green/blue,and brown/yellow respectively).$Al^{+3}$ is a representative element (non-transition metal) and does not form colored metaborates,thus it does not give a positive borax bead test.
