H9O4+ is often given as a reasonable configuration for the proton in solution. Using the Born equation and the equations for ion-dipole and ion-quadrupole interactions, show that the proton affinity of water must be about 180 kcal mole−1. The absolute individual heat of hydration of protons in water is −263 kcal mole−1.
