How does resonance make an acid stronger?

If an anion from an acid after losing its H+ has resonance, then this resulting anion is more stable because the negative charge of the overall anion is delocalized. Since nature favors stability, the acid would continue to give away more of its H+ if the anion is stable compared to other acids with less stable anions. And of course, an acid that dissociates more completely is a stronger acid.

Resonance is able to make an acid stronger because they are able to stabilize the conjugate base which will increase the acidity. It depends on the structure with delocalization for the anion. This will in turn make the acid be able to give off more H+ ions due to its stability with the conjugate base. If it is able to give off more H+, then it is much stronger as an acid.

In the resulting anion, resonance makes the anion more stable because it delocalizes the charge of the electrons, so it's distributed more evenly across the molecule. this makes it less likely to react with other surrounding molecules.

So if it doesn't have resonance the acid is automatically weaker?
