For a simple answer, an acid, likes do donate its H X + ions, and a base likes to give off its O H X − ions. The bond enthalpy of the A-H and B-OH bonds are low. Now the H X + a n d O H X − fuse to form a water molecule, giving rise to new bonds, hence is an exothermic process. dawn of man nexus mods

"WebThe “bond” that a water molecule makes is not a covalent or ionic bond. It is a strong attraction caused by water’s polarity. It takes energy to break the bonds between the molecules or ions of the solute. Energy is released when water molecules bond to the solute molecules or ions. " - H2so4 heat breaking bonds
