Question

anyone know how to do this and which choice is correct?thank you so much in advance.
Use the Henderson-Hasselbalch equation to calculate the pH of a buffer that is 0.350 M acetic acid and 0.250 M sodium acetate.

a.4.89
b.4.47
c.4.59
d.none of the above
is is not 4.74

Answer 1

Use the Henderson-Hasselbalch equation.
ou will need pKa for acetic acid. The base in the HH equation is 0.250 and the acid is 0.350 M. Plug in and turn the crank.

Answer 2

can i even work this? it seems like i need more before i can.

pH=pka+log(.250/.350)

because the question dosent give me anything else
