Toppr Admin · Accepted Answer

On heating borax- the colorless glassy bead formed consists of and boric oxide and sodium metaborate-Na2B4O7-10H2O-x2192-Na2B4O7-x2192-2NaBO2-B2O3-Hence- options A-C-andD are correct-

In borax bead test, which compound(s) is/are not formed?
Orthoborate
Metaborate
Double oxide
Tetraborate

On heating borax, the colorless glassy bead formed consists of and boric oxide and sodium metaborate.

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

Hence, options $A, C, a n d D$ are correct.
