MCQ
A buffer solution :
  • A
    Rapidly changes $\text{pH}$ due to addition of an acid.
  • ✓
    Resists changes in $\text{pH}.$
  • C
    Does not change $\text{pH}$ at all.
  • D
    Changes $\text{pH}$ only with the addition of a strong base.
✓

Answer

Correct option: B.
Resists changes in $\text{pH}.$
The solution of buffer resists changes in $\text{pH}.$
A buffer solution is defined as a solution which resists drastic changes in $\text{pH}$ upon the addition of a small amount of either an acid or a base.
