<u>Answer:</u> The pH of the buffer is 5.25
<u>Explanation:</u>
Let the volume of buffer solution be V
We know that:
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
We are given:
= negative logarithm of acid dissociation constant of weak acid = 4.90
pH = ?
Putting values in above equation, we get:
Hence, the pH of the buffer is 5.25
The answer is 23.5° but I guess 23° is closest
