enter image description here Amongst all hydroxybenzoic acids the ortho isomer is most acidic and the major reason is intramolecular H-bonding in the anion.

My question is that isn't the loss of proton destabilising the molecule more than stabilising it as earlier two H-bonds were possible but after deprotonation only one bond remains??
