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
