Calculation of pH of resulting mixture:
- The given pKb of NH4OH is 4.75, which means pKa of NH4OH is 14 - 4.75 = 9.25.
- When NH4OH reacts with HCl, it forms NH4Cl and H2O.
- The NH4Cl formed is a salt of weak base NH4OH and strong acid HCl.
- Since NH4Cl is a salt of weak base and strong acid, it will undergo hydrolysis in water.
- The hydrolysis reaction of NH4Cl will release H3O+ ions, resulting in the solution becoming acidic.

Calculating the pH:
- Given that the concentration of NH4OH and HCl is 0.1 M each.
- The initial concentration of NH4OH and HCl will be reduced due to the reaction between them.
- The moles of NH4OH and HCl will be equal in the mixture after the reaction.
- The moles of NH4OH used in the reaction will be equal to the moles of HCl used.
- The excess of NH4OH left will react with water to form NH3 and H3O+ ions.
- The concentration of NH3 formed can be calculated using the equilibrium constant expression.
- The concentration of H3O+ ions will also be formed due to the reaction of NH4Cl with water.
- Finally, the pH of the resulting mixture can be calculated using the concentration of H3O+ ions.
Therefore, the pH of the resulting mixture will be 5.28 (option 4).
