Homework Statement
Calculate the ph of a buffer made by mixing 50.0 mL of 0.10M of acetic acid with 50.0 mL of 0.10M sodium acetate. Use the Henderson-Hasselbalch equation.
Homework Equations
pH = pKa + log ([base]/[acid])
The Attempt at a Solution
I know how to do this problem if the 50.0 mL information isn't included. Does the volume even matter?
Heres my work without including the 50.0 mL
ICE TABLE
HC2H3O2 H3O+ C2H3O-
I .100 M 0.00 M .100M
C -x +x +x
E .100 - x x .100 + x
I get a concentration of 1.8E-5 M and pH will be 4.74
