Question

Heat of neutralisation of NaOH and HCl is -57.46. The heat of ionisation of water is in KJ is

Answer 1

For example, one source which gives the enthalpy change ofneutralisation of sodium hydroxide solution with HCl as -57.9 kJ mol-1, gives a value of -56.1 kJ mol-1 for sodium hydroxide solution being neutralised by ethanoic acid.
