Chemistry
1 answer:
In-s [12.5K]3 years ago
6 0

Answer:

D. a solution made by mixing 100 mL of 0.100 M CH3COOH and 50 mL of 0.100 M NaOH

Explanation:

Buffer solutions are the solutions which can resist the change in the pH up to some extent.

The pH of a buffer solution can be measured by the equation known as Henderson–Hasselbalch equation.

pH=pKa+log[base]/[acid]

Buffer solutions are the solutions of either weak acid and conjugate base of it or weak base and conjugate acid of it.

Hence, a weak acid and a strong base can result in weak acid and it's conjugate and can acts as a buffer.

Option D is correct.
