Part 1: Strong Acid with Strong Base

Figure 1: Titration Curve of a strong acid with a strong base. The curve represents an idealized titration of an equal amount strong acid (HCL) and strong monoprotic base (NaOH).

Estimated volume of titrant at equivalence point = ____25 25 25_____mL Estimated pH at equivalence point = ____ ____7_____ 7_____

Part 2: Weak Acid with Strong Base

Figure 2: Titration curve of a weak acid with a strong base. The curve represents the idealized titration of 0.1894 M CH3COOH, a weak acid and 0.2006 M NaOH, a strong base. Estimated volume of titrant at equivalence point = _____25 25 25____ ____ ____mL Estimated pH at equivalence point = _____9 9____

Part 3. Strong Acid with Weak Base Titration Curve

Figure 3: Titration curve of a strong acid with a weak base. The curve represents an idealized titration of 0.30 M HCL, a strong acid and 0.40 M NaHCO3, a weak base. Estimated volume of titrant at equivalence point = ___32 32 32______mL Estimated pH at equivalence point = ____3 3_____

Results and Calculati Calculations: ons: Here is a generic reaction that can be used to describe each of the three trials: acid (aq) + base (aq) → H2O (l) + ionic compound (aq) Using the above reaction, the information provided in the procedure for each reaction, and some stoichiometry to calculate the volume of the analyte that was used in each of the three titrations.

Part 1: Strong Acid with Strong Base

Volume of titrant = __50____ mL

0.3M NaOH x 0.050L = 0.3M HCL x V → V= 0.3M x 0.050L 0.30M V= 0.050L = 50mL

Part 2: Weak Acid with Strong Base Volume of titrant = ___50___ mL 0.2006M NaOH x 0.050L = 0.1894m HCl x V → V= 0.2006M x 0.050L 0.1894M V= 0.0529L = 53mL Part 3. Strong Acid with Weak Base

Volume of titrant = __50____ mL

0.3M HCl x 0.050L = 0.4M NaHCO3 x V → V= 0.3M x 0.050L 0.4M V= 0.0375L = 38mL
