Given that the pKa for Acetic Acid is 4.77, calculate the expected pH of the buffer solutions using the Henderson-Hasselbalch equation and the concentrations of Acetic Acid and Acetate added to the 250 ml Erlenmeyer flask:

pH = pKa + log { [base] / [acid] }
= ?

Moles of base = mass of NaC2H3O2 / GMW of NaC2H3O2
Moles of acid = volume of C2H4O2 in litres x molarity of C2H4O2

74ml of 0.1M Acetic Acid C2H4O2.
1.1g of Sodium Acetate NaC2H3O2.
26ml of Water H2O
