Outline:Determination of pKa of Acetic acid About Henderson-Hasselbalch equation. Retrieve chemicals from the Stockroom Explorer. Retrieve the glassware from the glassware menu. Use precise transfer mode to transfer the chemicals. Dilute 1 molar acetic acid to 0.1 molar acetic acid. Titrate 0.1 molar sodium hydroxide against 0.1 molar acetic acid. Note the change in pH values on addition of sodium hydroxide to acetic acid. Plot a graph of volume of sodium hydroxide added versus pH values. Find pH at half-equivalence and equivalence points. Calculate the Ka and pKa values.
