Properly and volumetrically performing acid/base titrations is a critical technique in instrumental and analytical processes. In this lab, you will first make your own NaOH solution, standardize it using conductivity, thus getting a molarity to 4 significant figures, then you'll use that standardized base solution to titrate a solution of phosphoric acid. In the end, you reproduce the pKa's of phosphoric acid's end points.
