Question
1.Suppose you are titrating a 0.3500 g sample of an unknown weak acid dissolved in water and diluted to 20.00mL. You find it takes 38.52 mL of 0.2100 M KOH to reach an endpoint. You also notice that when 19.26 mL of KOH have been added (halfway to the endpoint) the pH of the solution is 3.456.
a.What is the molar mass of the acid?
b.What is the pKa of the acid.
c.What was the pH when 10.00 mL of the base had been added?
d.What was the pH when 30.00 mL of the base had been added?
e.What is the pH at the equivalence point?
