Question
A buffer solution is prepared by mixing ′a′ moles of CH3COONa and ′b′ moles of CH3COOH such that (a + b) = 1, into water to make 1L buffer solution. If the buffer capacity of this buffer solution is plotted against moles of salt CH3COONa (a) then the plot obtained will be (to the scale) approximately. (As shown in figure in options)
Options
A.
B.
C.
D.
Solution
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
Hence the result.and a = b = 0.5, BC = 2.303
= 0.57Create a free account to view solution
