You were carefully doing your potentiometric titration of vinegar with NaOH when you suddenly had to take a break and order the new BTS McNuggets bundle. When you took a break, you left your titration at the pH within the buffer region. While you were away, your sibling decided to pull a terrible prank and poured 10.0mL distilled water into your reaction flask. You had no knowledge of this incidence. When you return to continue your experiment, you will see (increase, decrease, no change) in pH as a result of the dilution of the buffer system because

3 Title: Acid-Base Titration using the pH Meter (Potentiometric Titration) Titrations can be done without the use of indicators by utilizing pH meters. The method is very similar to the standard acid/base titration; however, the pH is recorded as the titration proceeds. A plot of pH against volume of reagent added is used to determine the equivalence point of the reaction. 1. Explain how equivalence point, pKa and subsequently, Ka can be obtained from a plot pH vs volume of reagent added
One of the titration curves in the diagram represents the titration of an aqueous sample of Na₂CO3 with strong acid; the other represents the titration of an aqueous sample of NaHCO3 with the same acid. Match the curves to the appropriate compound. A NaHCO3 14 B Na2CO3 12 B 10 a 8 A b 6 4 с 2 0 Volume of strong acid (ml) Hd

If you have determined your pKa values and located the equivalence points on the graph, and then you use a stronger concentration of base to titrate the unknown acids, could you successfully locate the equivalence points and pKa values? If so, how and how you would have to adjust volumen(if needed) to have a successful titration
). You are running an experiment and need to keep your solution within a certain pH range: 3.5 +/- 1pH unit. Choose a buffer system (e.g. a conjugate acid/base) with a pKa in the appropriate range.. Assuming you have 0.2M stock solutions of the acid and conjugate base, calculate the L of each need to make 400 mL of buffer. Describe clearly your protocol for making the buffer solution to the desired pH. Calculate pH for the following. Add 100 mL of 0.100 M HCl to pure water Add 100 mL of 0.100 M HCl to the 400 mL of buffer you made Add 100 mL of 0.100 M NaOH to pure water Add 100 mL of 0.100 M NaOH to the 400 mL of buffer you made Please complete the problem
Please complete the calculation of the pH of the equivalence point below. Concentration of NaOH solution = 0.1 mol dm-3. Mean titre (NaOH solution) = 18.95 cm3. Amount of NaOH = 0.00189 moles. Molar ratio of NaOH:aspirin = 1:1. Amount of aspirin = 0.00189 moles. Mass of aspirin (in titration) = 0.341 g. |Mass of aspirin (per tablet) = 0.341 g.

Use the oxidation number method to balance the following: Sn + PbCl2 = SnCl2 + Pb (neutral conditions)
Recall what you know about the neutralization of weak and strong acids and bases. Is the pH at the end point of this titration likely to be less than, approximately, or greater than 7?
