The neutralisation of a strong acid by a strong base liberates an amount of energy per mole of H⁺ that
Options
(a) depends upon which catalyst is used
(b) depends upon the temperature at which the reaction takes place
(c) depends upon which acid and base are involved
(d) is always is same
Correct Answer:
is always is same
Explanation:
Strong acids and strong base dissociate completely in solution to give H⁺ and OH⁻ in solution.
e.g. NaOH → Na⁺ + OH⁻,
HCl → H⁺ + Cl⁻. So the amount of energy liberated is always the same, as the reaction involved is , H⁺ + OH⁻ → H₂O.
