Generate the hypothetical titration curve for the titration of 50.00 mL of 0.0500 M HCl with 0.1000 M NaOH at 25 degrees Celsius. Hint: For this type of problem, first calculate the volume of the titrant you need to add to reach equivalence point (VOH-=Veq), and then calculaett the pH at: 1. Initial point (before adding the titrant VOH-=0) 2. Before equivalence point (0<VOH-<Veq) ex. V=10.00 mL 3. At equivalence point (VOH-=Veq) 4. After equivalence point (VOH->Veq) ex. V= 25.10...
