What is the value of pOH if a buffer solution is prepared by mixing equal volumes of 0.4 M NH ₄ OH and 0.5 M NH ₄ Cl solutions. ( pK _ b =4.730 )
Options
- A6.0
- B4.83
- C10.42
- D7.81
Correct answer
B. 4.83
Step-by-step solution
For a basic buffer, aligned pOH & = pK _ b + [ Salt ] [ Base ] & =4.730+ ( 0.5 0.4 ) & =4.83 aligned
