Question

The radical can be identified by borax bead test is (A)  Mg2+  (B)  Ca2+  (C)  Cu+  (D)  Cu2+

Tardigrade Admin · Accepted Answer

Borax bead test is given by only those transition metal ions or salts which contain unpaired electrons. Among the given ions, only Cu+ and Cu2+ are transition metal ions. Out of these only Cu2+ contains unpaired electron, hence it gives borax bead test.

$M g^{2 +}$

$C a^{2 +}$

$C u^{+}$

$C u^{2 +}$

Borax bead test is given by only those transition metal ions or salts which contain unpaired electrons. Among the given ions, only $C u^{+}$ and $C u^{2 +}$ are transition metal ions. Out of these only $C u^{2 +}$ contains unpaired electron, hence it gives borax bead test.
