D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C

On diluting a buffer solution, its pH

The solution which consumes [H^(+)] or [OH^(-)] or both simultaneously from externally added base in order to give negligible change in pH , is known as buffer solution. In general, the solution resists the change in pH. Buffer solution does not mean that there does not occur a pH change in pH. Buffer solution des not mean that there does not occur a pH change at all. It implies the pH change occurs but in neglibible amount. There are two types of buffer (i) Acidic buffer: it is a mixture of weak acid and its salt acid strong base. (ii) Basic buffer : It is a mixture of weak base and its salt with strong acid. pH of 0.01 M (NH_(4))_(2)SO_(4) and 0.02 M NH_(4)OH buffer ( pK_(a) of NH_(4^(+)) = 9.26) is

Statement-1: pH value of acidic buffer solution changes , If buffer solution is diluted upto very large extent. Statement-2: [H^(+)] decreases due to change in concentration as well as alpha increases and decreases in concentration is more as compared to increases in alpha .

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) .
