Question
When 0.002 mol of acid is added to 250 mL of a buffer solution, pH decreas by 0.02 units. The buffer capacity of the system is
Options
A.0.1
B.0.2
C.0.3
D.0.4
Solution
Buffer capacity = 
[Acid] =
= 0.008 M
Buffer capacity =
= 0.4
[Acid] =
= 0.008 MBuffer capacity =
= 0.4Create a free account to view solution
