Question

1. What is the enthalpy of neutralisation of a strong acid and a strong base ?​

Answer 1

Answer:

Enthalpy changes of neutralization are always negative - heat is released when an acid and and alkali react. For reactions involving strong acids and alkalis, the values are always very closely similar, with values between -57 and -58 kJ mol-1.

Answer 2

the enthalpy of neutralisation of a strong acid and a strong base is always constant.

1. the enthalpy of neutralization of a strong acid and a strong base is always considered constant because the strong acids and bases completely gets ionized in dilute solution.
2. enthalpy of neutralization is always negative.
3. so the value of enthalpy of neutralization is -57 kJ mol-1
4. when a strong acid or base gets dilutes it is completely ionized in the solution breaking in positive and negative ions
5. it is an endothermic reaction which releases energy.
