Heat of neutralization of a strong acid by a strong base is equal to ∆H of
A
H+ + OH+→ H2O
B
H2O + H+→ H3O+
C
2H2 + O2 = 2H2O
D
CH3COOH+ NaOH = CH3COONa + H2O
Answer
H+ + OH+→ H2O
Explanation
Solution
Since heat neutralization of strong acid and strong base is equal to the of formation of water.
i.e., NaOH + HCl → NaCl + H2O + Q
Were Q = heat of neutralization
⇒ Na+ + OH– + H+ + Cl– → Na++Cl– + H2O + Q
⇒ H+ + OH– → H2O + Q
