When borax is heated with CoO on a platinum loop, blue coloured bead formed is largely due to
When borax is heated with CoO on a platinum loop, blue coloured bead formed is largely due to
Updated On: Sep 13, 2024
\(B_2O_3\)
\(CO(BO_2)_2\)
\(COB_4O_7\)
\(CO[B_4O_5(OH)_4]\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
\(Na_2B_4O_7→ 2NaBO_2+B_2O_3\)
\(B_2O_3+CoO→Co(BO_2)_2\)
Cobalt metaborate (Blue Coloured)
So, the correct option is (B): \(Co(BO_2)_2\).

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
