Hence 200 ml of NH4Cl should be added to 100 ml solution of NH4OH.
Explanation:
Correct statement:
What volume of 0.2 M NH4Cl solution should be added to 100 ml of 0.1 M NH4OH solution to produce a buffer solution of pH = 8.7 ?
Solution:
pH = 8.7 ⇒ pOH = 5.3
Basic Buffer
pOH = pKb + log [Salt / Base]
Salt / Base = 4
If volume of salt = V ml
V x 0.2 / 100 x 0.1 = 4
V = 200 ml
Hence 200 ml of NH4Cl should be added to 100 ml solution of NH4OH.
