When acid and alcohol react then acid loss OH- ion and alcohol loss H+ion, acid has tendency to loss H+ . plese explain with reason.

there no acid base rxn. H+ lose in acid base rxn . alcohol attack at carboxylic acid and rxn proceed accordingly nucleophilic elimination ....see ester formation mechanism

and acid which loss OH- while loss of H+ make more stable due to resonanace but loss OH- ion why
