A buffer solution is prepared by mixing 'a' moles of CH 3 COONa and 'b' moles of CH 3 COOH such that (a + b) = 1, into water to make 1L buffer solution. If the instantaneous (differential) buffer capacity of this buffer solution is plotted against moles of salt CH 3 COONa
A
, then the plot obtained will be (to the scale) approximately : 
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Maximum buffer capacity of a solution is given by, buffer capacity = 2.303 
. Hence the result. and a = b = 0.5, BC = 2.303 × 
= 0.57
