Question

Aqueous solution of borax reacts with 2 mol of acids. This is because of?

• A. Formation of 2 mol of $B(OH{)}_3$ only.
• B. Formation of 2 mol of ${\left[B\right(OH{)}_4]}^{-}$ only.
• C. Formation of 1 mol each of $B(OH{)}_3$ and ${\left[B\right(OH{)}_4]}^{-}$ only.
• D. Formation of 2 mol each of ${\left[B\right(OH{)}_4]}^{-}$ and $B(OH{)}_3$, of which ${\left[B\right(OH{)}_4]}^{-}$ reacts with acid.

Answer 1

The correct option is D Formation of 2 mol each of ${\left[B\right(OH{)}_4]}^{-}$ and $B(OH{)}_3$, of which ${\left[B\right(OH{)}_4]}^{-}$ reacts with acid.
