Higher the amount of acid or base used to product a deinite change of pH in a buffer solution, higher will be its buffe capacity. Buffer capcity of solution is maximum under the following conditions
[Salt] = [Acid](in acid buffer)
[Salt] = [Base] (in base capacity]
pH of buffer solution lies inthe range given below `pH = pH_(a) +-1`
In other words,any buffer solution can be used as buffer up to two pH units only, depending upon the value of `pK_(a)` or `pK_(b)`. A buffer is said to be efficient when `pH = pK_(a)` or `pOH = pK_(b)`
Acifity of `BF_(3)` can be explained on the basis of which of the following concepts

A

Arrehenius concept

B

Bronsted Lowry concept

C

Lewis concept

D

Bronsted Lowry as well as Lewis concept
