Question

When borax is heated strongly, it gives (A)  BaBO2  (B)  B2O3  (C)  B3N3H6  (D)  Na2B-4O7

Borax, when heated strongly, gets converted into a glassy bead, called borax bead, which is a mixture of sodium metaborate and boric anhydride. Na 2 B 4 O 7 ⋅ 10 H 2 O stackrelΔ longrightarrow Na 2 B 4 O 7+10 H 2 O <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/0f33e0f581f24d950b9065b9f545bbe6-.png" />
