Question

Standard enthalpy of neutralisation vs enthalpy of neutralisation

Answer 1

Hey..!

It is a special case of the enthalpy of reaction. It is defined as the energy released with the formation of 1 mole of water. The enthalpy change for this reaction is -57.62 kJ/mol at 25 °C. For weak acids or bases, the heat of neutralization is pH dependent.

Thanks.. :)

Answer 2

$\huge\mathfrak\color{blue}{Answer}$

The enthalpy of neutralization (ΔHn) is the change in enthalpy that occurs when one equivalent of an acid and a base undergo a neutralization reaction to form water and a salt. ... The enthalpy change for this reaction is -57.62 kJ/mol at 25 °C. For weak acids or bases, the heat of neutralization is pH-dependent
