The standard enthalpies of formation of ions in aqueous solutions are obtained by arbitrarily assigning a value of zero to H+ ions; that is, = [H+{0)] = 0.

(a) For the following reaction

calculate for the Cl- ion. (b) Given that for OH- ion is –229.6 kJ/mol, calculate the enthalpy of neutralization when 1 mole of a strong monoprotic acid (such as HCl) is titrated by 1 mole of a strong base (such as KOH) at 25°C.
