The enthalpy of neutralization of a strong acid by a strong base is -57.6 kJ/mol. The enthalpy of formation of water is -285.9 kJ/mol. The enthalpy of formation of the aqueous hydroxyl ion is
Options:
Answer:
C
Solution:
H+(aq) + OH-(aq) → H2O(l); ΔH = -57.6 kJ. With Δf H(H+, aq) = 0: Δf H(OH-) = -285.9 - (-57.6) = -228.3 kJ/mol. This is option (c).
