Buffer Capacity

Question

Buffer capacity of a buffer solution is x, the volume of 1 M NaOH added to 100 mL of this solution if the change of pH by 1 is

Easy

A

0.1 x mL
B

10 x mL
C

100 x mL
D

x mL

Solution

Buffer capacity is the no. of moles or gram equivalents of strong acid or base added to 1Lit of soln.to change $P^{H}$ of buffer soln.by 1unit.
buffer capacity of solution = x
$∴ Mole of NaOH$ is required for 1 L solution = x
Now, $\frac{100}{1000} (x)=.1x$
0.1x = 1 x V
$\Rightarrow$ V = 0.1 x 1000 = 100x ml
