Question

Complete these brønsted-lowry reaction hpo42- + f-

Answer 1

Answer : The reaction is,

$HPO^{2-}_4+F^-\rightarrow HF+PO^{2-}_4$

Explanation :

The complete bronsted-lowry reaction is,

$HPO^{2-}_4+F^-\rightarrow HF+PO^{2-}_4$

Bronsted-lowry reaction : It is an acid-base reaction in which a proton is transferred from an acid to base. That means acid donates protons and base accept protons.

In the given reaction, $HPO^{2-}_4$ donates a proton to $F^-$ and they form $HF$ as an acid and $PO^{2-}_4$ as base.

Answer 2

Answer : The brønsted-lowry reaction is,

$HPO^{2-}_4+F^-\rightarrow HF+PO^{3-}_4$

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

The complete bronsted-lowry reaction is,

$HPO^{2-}_4+F^-\rightarrow HF+PO^{3-}_4$

In the given reaction, $HPO^{2-}_4$ donates a proton or hydrogen to $F^-$ and they form $HF$ as an acid and $PO^{3-}_4$ as base.
