Question

Define enthalpy change of neutralization

Answer 1

The enthalpy of neutralization (ΔHn) is the change in enthalpy that occurs when one equivalent of an acid and one equivalent of a base undergo aneutralization reaction to form water and a salt. ... It is defined as the energy released with the formation of 1 mole of water.
