Answer:

CH₃COOH ⇄ CH₃COO⁻ + H⁺

Explanation:

Hello,

Acetic acid is a weak acid that dissociates to give acetate and hydrogen ion in the solution. The system is at equilibrium with each other can the extent of dissociation can be given as a constant which is usually expressed as pKa.

pKa = -Log(Ka)

A buffer solution is a solution that avoids or resist a change in the pH value when an alkali or acid is added to the solution. Buffer solution usually shifts equilibrium so as to annul the effect of either the alkali or acid.

Equation of reaction.

CH₃COOH ⇄ CH₃COO⁻ + H⁺

Ka = [CH₃COO⁻][H⁺] ÷ [CH₃COOH]

Histrionicus

The equilibrium equation for the acetic acid/acetate buffer system -  

CH₃CO₂H + H₂O ⇄ CH₃CO₂⁻ + H₃O⁺

An acid buffer is a solution that contains roughly the same concentrations of a weak acid and its conjugate base.  

  • an acetate buffer contains roughly equal concentrations of acetic acid and acetate ion.
  • Both are in chemical equilibrium with each other.

The equation is:  

CH₃CO₂H + H₂O ⇄ CH₃CO₂⁻ + H₃O⁺  

where CH₃CO₂H - acetic acid  

and, CH₃CO₂⁻ acetate ion  

Thus, CH₃CO₂H + H₂O ⇄ CH₃CO₂⁻ + H₃O⁺ is the equilibrium equation for the acetic acid/acetate buffer system.
