Question

Answer the following in one sentence :

Write one property of a buffer solution.

Short Note

Solution

Properties of buffer solution:

i. When a small amount of strong acid (or strong base) is added to a buffer solution, there is no significant change in the value of pH.

ii. The pH of a buffer solution is independent of the volume of the solution. Hence, the dilution of a buffer solution will not change its pH.

iii. The pH of a buffer solution does not change even if it is kept for a long time.
