🤓 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 HCHO_{2}/NaCHO_{2 }buffer

Recall the Henderson-Hasselbalch equation:

$\overline{){\mathbf{pH}}{\mathbf{=}}{{\mathbf{pK}}}_{{\mathbf{a}}}{\mathbf{+}}{\mathbf{log}}\left(\frac{\mathbf{conjugate}\mathbf{}\mathbf{base}}{\mathbf{weak}\mathbf{}\mathbf{acid}}\right)}$

- Using this particular equation, we can calculate or estimate pH by getting the pka and ratio of the concentration of the c.base (NaCHO
_{2}) and the weak acid (HCHO_{2})

If the p*K _{a}* of HCHO

A) [HCHO

B) [HCHO_{2}] > [NaCHO_{2}]

C) [HCHO_{2}] = [NaCHO_{2}]

D) [HCHO_{2}] >> [NaCHO_{2}]

E) It is not possible to make a buffer of this pH from HCHO _{2} and NaCHO_{2}
