Question

The heat of neutralization of any strong acid and a strong base is nearly equal to:

• A. -75.3 kJ
• B. +57.3 kJ
• C. -57.3 kJ
• D. +75.3 kJ

Answer 1

Answer: (C)

-57.3 kJ

Heat of neutralization of strong acid by strong base is always constant because it is infact heat of formation of $H_{2}O$ by $H^{+}$ and $O{H}^{-}$ ions. Its value is nearly equal to -57.3 kJ.

The correct answer is -57.3 kJ.
