Examine the following reaction.

hbrwater—→h++br−

what process is being shown?

hydronium formation
neutralization
acid dissociation
base dissociation

acid dissociation

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

For the given chemical equation:

Here, is loosing a proton, thus it is considered as an acid and the reaction is acid dissociation.

Hydroium ion is

Neutralization reaction is a chemical reaction in which an acid reacts with base to produce salt and water.

Thus the reaction is acid dissociation.
