WebThe buffer you describe can be illustrated by the following equilibrium: CH3COOH(aq) + H2O(l) = CH3COO-(aq) + H3O+(aq) CH3COOH is a weak acid, while CH3COO- is a weak base (the Na+ is not important to the buffer, it can be considered a spectator ion). The pH of this buffer depends on the [CH3COOH] and the [CH3COO-].
