PH of the new solution

A buffer is formed by mixing 100 mL of 0.1 M NH4Cl with 50 mL of 0.3 M NH3. To this solution 12 mL of 0.1 M NaOH is added. What is the approximate pH of the new solution after neutralization? Assume a Kb of 1.8 × 10^?5 for the weak base.1. 9.372. 4.483. 4.634. 9.525. 9.44Q) A buffer is formed by mixing 100 mL of 0.1 M NH4Cl with 50 mL of 0.3 M NH3.
