Solution

Borax is formulated as $N a_{2} B_{4} O_{7} .10 H_{2} O$ .
Borax bead test is used in the identification of certain metals. Some metallic ions that cannot be identified by a flame test identified by a bead test. The test can also be used to confirm the results of a flame test. A small loop is formed at the end of a platinum wire. The loop is cleaned with concentrated hydrochloric acid and dipped in powdered borax, then heated in the flame of a Bunsen burner until the borax melts, forming a bead. The bead is dipped into a tiny amount of the compound to be tested and is reheated in the flame. The metal borate that is formed colors the bead. Some metals and the colors they produce in an oxidizing flame are: chromium, green; cobalt, blue; copper, blue-green; iron, yellow to brown; manganese, violet; nickel, reddish-brown.

$N a_{2} B_{4} O_{7} .10 H_{2} O + h e a t \to N a_{2} B_{4} O_{7} \to$ on heating $\to 2 N a B O_{2} + B_{2} O_{3}$

A test similar to the borax bead test is often made using microcosmic salt.
