Define Enthalpy of neutralisation. Enthalpy of neutralisation of strong acids and strong base almost same. Explain
Enthalpy of Neutralization: -
Enthalpy means change in heat energy. Neutralization means
when acid and base mixed together then salt is formed and by product is water
and heat energy is also release.
By definition: -
It is defined as when one equivalent of acid and one
equivalent of base mixed together to form salt and water (neutralization reaction)
then change in enthalpy is known as Enthalpy of neutralization.
Case: -
If strong acid and strong base react with each other then change in enthalpy is similar or approx same.
Because strong acid and strong base is fully ionise in water.
Considering neutralisation of strong acid by strong bases, It will be seen that in every case, the neutralization reaction is same as it simply involves the combination of H+ ions and OH- ions to form unionise water H2o,. It is expected, therefore that the enthalpy of neutralization of every strong acid by strong base and vice versa should e identical.
