Can resonance structures determine the strength of an acid? Or is there no correlation between both?

the strength of an acid has to do with how weak the bonds are in comparison to other acids. usually, the main factor that determines this is shielding (because there is a larger electron cloud). i dont think resonance has as big of an impact on acid strength versus something like shielding

Resonance generally makes a molecule stable, therefore it would be less likely to react if put into water. So I would say in general, resonance doesn't correlate with how strong an acid is.

I believe resonance stabilises a compound. Strength depends on the length of the bond, and other factors like electron repulsion, radius etc.
