MCQ
The $pH$ of an acidic buffer mixture is
- A$ > 7$
- B$ < 7$
- C$=7$
- ✓Depends upon $K_a$ of acid
✓
Answer
Correct option: D.
Depends upon $K_a$ of acid
d
$pH = p{K_a} + \log \frac{{\left[ {salt} \right]}}{{\left[ {Acid} \right]}}$
$pH = p{K_a} + \log \frac{{\left[ {salt} \right]}}{{\left[ {Acid} \right]}}$
