Witryna17 wrz 2016 · The reaction with sodium is a redox reaction (note the changing oxidation state of hydrogen from +1 to 0), whereas that with NaOH is merely acid-base. As for the reaction with NaOH, it will certainly proceed, but in general will probably not go to completion (see also vapid's comment on the answer). – orthocresol Sep 17, 2016 at … WitrynaSo when NaOH reacts with H2O, the enthalpy of the solution is -40 kJ ± 7 kJ. Since the enthalpy value is negative, it means that energy is lost, probably due to heat to the surrounding, which in this case was the water. Since it gives away energy, it is an exothermic reaction. The value of -40 kJ ± 7 kJ can be supported by the literary values. kering pronunciationWitrynaEnthalpy of solution of N aOH (solid ) in water is −41.6 kJ mol−1 .
