Workshop 5: Titration Curves A pH or titration curve can be produced by plotting the pH of a solution (containing an analyte) versus the volume of added The equivalence or end point of a titration occurs when enough titrant has been added to consume all the acid or base initially present in the analyte.You know you have reached the endpoint when you see a significant change in the pH of the solution. Part Lets begin by analyzing a titration curve...
Suppose you performed a titration of a weak acid and you found that the equivalence point occurred at 12.3 mL of added NaOH. At what volume would you use the pH to determine the pKa of the acid? Enter your answer numerically to three significant figures
