- AStrong acid + its salt of strong base
- BWeak acid + its salt of weak base
- CStrong acid + its salt of weak base
- ✓Weak acid + its salt of strong base
✓
Answer
Correct option: D.
Weak acid + its salt of strong base
d
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.
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.
