Question

Acetic acid ($C{H}_{3}COOH$) can be a buffer, similar to carbonic acid. Write the dissociation reaction, identifying the acid, base, H⁺acceptor, and H⁺donor.

Short answer

The acetic acid undergoes a dissociation reaction to produce a base and a hydrogen ion. The base made from acetic acid is$C{H}_{3}CO{O}^{-}$. The hydrogen ion donor is the acetic acid. The hydrogen ion acceptor is the base.

Step-by-step solution

Description of the dissociation reaction

The reaction in which one molecule splits into two components is known as dissociation reaction. In general, the dissociation of acids leads to the formation of hydrogen ions.

Description of acetic acid

Acetic acid is carboxylic acid which is a colorless liquid. The commercial application of acetic acid is vinegar.The molecular formula for acetic acid is$C{H}_{3}COOH$. The acetic acid has a boiling point of 116°C, and the melting point is 16.6^°C.

Components of acetic acid dissociation

The dissociation reaction of acetic acid is as follows.

$C{H}_{3}COOH\to C{H}_{3}CO{O}^{-}+H^{+}$

The reactant acetic acid is the acid.

H⁺ donor is the component that can donate the hydrogen ion. The component that has excess hydrogen ions in it is known as hydrogen donor. Here, the acid is the donor of hydrogen ions.

Usually, acid tends to lose the proton to become a base. It is known as a hydrogen ion acceptor. Here the acetic acid is the hydrogen ion donor.

The $C{H}_{3}CO{O}^{-}$ has anegative charge which makes it the electron acceptor. This will act as the H⁺ ion acceptor.
