MCQ
Buffer Solution is prepared by mixing $.........$
- ✓Weak acid and its salt of strong base.
- BStrong acid $+$ its salt of strong base.
- CWeak acid $+$ its salt of weak base.
- DStrong base $+$ its salts of strong acid.
✓
Answer
Correct option: A.
Weak acid and its salt of strong base.
A solution that resists change in $pH$ value upon addition of a small amount of strong acid or base $($less than $1 \%)$ or when the solution is diluted is called buffer solution.
An acidic buffer solution consists of a solution of a weak acid and its salt with a strong base. while basic buffer solution consists of a mixture of a weak base and its salt with strong acid.
An acidic buffer solution consists of a solution of a weak acid and its salt with a strong base. while basic buffer solution consists of a mixture of a weak base and its salt with strong acid.
