# Dissociation reaction notation

This equation has been described as an equilibrium in an article, how would you explain it to someone with not a lot of understanding of it.

The equation is: $\ce{CH3COOH <-> CH3COO- + H+}$

Although the description is of an equilibrium, it can be clearly seen that it is a resonance arrow. So how would you describe it?

No, no it's not a resonance arrow my friend, it has to be an arrow for equilibrium because it is a reaction equation of $\ce{CH3COOH}$ in its aqueous solution. It will dissociate feebly into its constituent ions because its a really weak acid. Thus establishing equilibrium quite a lot first.
