    Once again I am reminded you enthalpy of neutralization is energy released for formation of 1 mole of water

  • Suman Kumar thankyou
    Now HF & NaOH comes under strong acid so it releases 57.1 only.

    buy mam in one video I have seen that HF +naoh enthalpy of neutralisation is higher because there is enthalpy of hydration also involeves
  • Suman Kumar
    Strong acid & strong base completely dissociate so it releases 57.1 kj but weak acid & weak base doesn't dissociate completely so it releases less energy

    When ever there is formation of 1 mole of H2O from acid-base neutralization amount of energy released is 57.1 Kj . Enthalpy of neutralization is defined as neutralization of 1 gra...

    and if there is weak acid and weak base then dissociation is partial so we have to take help of some mineral acid or some alkali so enthalpy of neetralisation is less than -57.1kj/...

  • Priyanshu kumar thankyou
    so always keep in mind when there is strong acid and strong base...then -57.1 Kj/mole of heat is releases

    sir but I'm one video I have seen that enthalpy of neutrilazation of HF and naoh is greater because here is enthalpy of hydration also involves
  • Priyanshu kumar Best Answer
    see shweta when neutralisation occurs between strong acid and strong base then there is complete disaociation so no cation and anion occurs in the complete reaction rather H+ + OH-...
