Complete the equation to show how hydrofluoric acid, HF, acts as a Brønsted-Lowry acid in water. Balanced equation:

shepuryov [24]

Answer : The balanced equation is,

$HF+H_2O\rightleftharpoons H_3O^++F^-$

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.

The balanced chemical reaction will be,

$HF+H_2O\rightleftharpoons H_3O^++F^-$

In this reaction, hydrofluoric acid is act as a Bronsted Lowry-acid because it donate one hydrogen ion to $H_2O$ and $H_3O^+$ is act as a Bronsted Lowry-base because it accept one hydrogen ion from $HF$ .
