🤓 Based on our data, we think this question is relevant for Professor Ishchuk's class at Sacramento City College.
For this problem, we have to check which among the statements are true regarding a HCHO2/NaCHO2 buffer
Recall the Henderson-Hasselbalch equation:
If the pKa of HCHO2 is 3.74 and the pH of an HCHO 2/NaCHO2 solution is 3.89, which of the following is true?
A) [HCHO2] < [NaCHO2]
B) [HCHO2] > [NaCHO2]
C) [HCHO2] = [NaCHO2]
D) [HCHO2] >> [NaCHO2]
E) It is not possible to make a buffer of this pH from HCHO 2 and NaCHO2
