Answer:
0.387 g
Explanation:
pH of the buffer = 1
V = Volume of solution = 100 mL
[HA] = Molarity of HA = 0.1 M
= Acid dissociation constant =
(assuming base as )
Molar mass of base = 322.2 g/mol
pKa is given by
From the Henderson-Hasselbalch equation we get
Moles of base
Mass of base is given by
The required mass of the base is 0.387 g.
