HNO3(aq) + NaOH(aq) → NaNO3(aq) + H2O(l)
ΔH°rxn = -55.83 kJ/mol
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
HNO3(aq) + NaOH(aq) → NaNO3(aq) + H2O(l)
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
NH4+(aq) + NaOH(aq) → NH3(aq) + Na+(aq) + H2O(l)
In the third equation NH4+(aq) is acting as an acid. Based on the value of ΔH˚ for this reaction, do you think it is a strong or a weak acid?
