Write appropraite equations to support this explanation?

Question

Explain why would you expect that H neutzn for HBr reacting with NaOH solution and H neutzn for HNO3 reacting with KHO solution would be identical.

Answer 1

Both HBr and HNO3 have one ionizable H in each molecule.

Both NaOH and KOH have one ionizable OH in each molecule.

Therefore HBr and NaOH will ionize in a 1 : 1 ratio, and HNO3 and KOH will ionize in a 1 : 1 ratio.

Answer 2

The actual equation that is going on is simply H+ + OH- ----> H2O, often called the ionic eqution for neutralisation.
Since the Br- and Na+ and (NO3)- and K+ ions aren't doing anything except balance out charges in solution, you would expect the enthalpy of neutralisation of any strong acid and strong alkali to be the same. HBr and HNO3 are strong acids, and NaOH and KOH are strong alkalis.
