C.A. Yates was given a 50.0mL sample of the weak acid. The knownconcentration of the weak acid is .25M. After preparing a buret hedelivers 25.0mL of the weak acid into a 100mL Erlenmyer flask. Hethen titrated this solution using a standardized solution of .15 MNaOH.
a)How many mole of the weak acid were added to the beaker?
b)How many moles of NaOH are required to neutralize (reach theequivalence point) the sample of weak acid)?
c)How many milliliters of the NaOH are required to neutralizesample of the w3eak acid?
d) How many moles of NaOH have been added at one half of thevolume in part 'C' (volume at the half, equivalence point)?
e) How many moles of the weak acid have reacted at the halfequivalence point?
f) Calculate the pH of the soluation at the half equivalencepoint.
g) Explain how the pH at the half equivalence point is relatedto K_a, for the weak acid.
