The pH of Weak Acid and Base Solutions — Examples - Expii
A solution of NH4Cl and NH4OH acts as a buffer.
The enthalpy of neutralisation of NH4OH with HCl is - 51.46kJ/ mol^-1 and the enthalpy of neutralisation of NaOH with HCl is - 55.90kJ/ mol^-1 .The enthalpy of ionisation of NH4OH is:
SOLVED: NHANOz is the conjugate acid of the weak base ammonium hydroxide (NHAOH) and the strong acid nitric acid (HNO3). Kb for ammonium hydroxide is 1.8 x 10-5 according to the following
