- List the observations of a manual titration experiment and explain your expectations. This should include color change and when the equivalence point (endpoint) might be reached. When do you stop and why.Using a pH meter, verify that 100 mL of distilled water is neutral.Dissolve 50.0 mg of naproxen drug substance, accurately weighed, in 50 mL of methanol. Add 25 mL of the neutralized water and mix. Add two drops ofphenolphthalein as the indicator. What is the blank sample in this experiment? How many sample and blank titrations are required for this experiment? Use the equation below to calculate your expected end-point volume. Each mL of 0.01 N sodium hydroxide is equivalent to 2.303 mg of naproxen,C14H14O3Thank you! Data included in picture! No hand drawn graphs!! Determine the equivalence point of sudsy ammonia/citric acid reaction by graphing the titration data (pH vs volume citric acid) from Table 1: No Indicator Data Table. Draw a green arrow (use ‘Insert Shape’ feature to do this once you have copied your graph from Excel) on your graph indicating the data point that represents your equivalence point. Use a graphing software to create the x-y scatter plot showing the pH of the experimental solution as a function of the volume of citric acid (the titrant) added for the titration in Part 4. On your graph, the x-axis should be the volume of citric acid added (mL), and the y-axis should be the pH of the experimental solution at that volume. Do NOT connect your points; no trend line needed and make sure to: · Label the axes including the units in parentheses. · Include a figure legend (text below the graph) explaining the data in your graph that includes the arrow…

- Explain why the volume of water added to the vinegar before the titration started did not need to be exactly measured or recorded ?A buffer contains significant amounts of acetic acid and sodium acetate. a)Write an equation showing how this buffer neutralizes added acid (HBr(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. b)Write an equation showing how this buffer neutralizes added base (KOH(aq) Express your answer as a chemical equation. Identify all of the phases in your answer.The toughest part about titration is adding just enough of the titrant (NaOH, in this case). If you add the NaOH too quickly, you will likely end up adding too much ("overshooting the endpoint"). Alternatively, you could add it very slowly, drop-by-drop, but with this approach, you'll probably run out of time in the lab! The best option is to know in advance a rough idea of how much you'll need to add. Get close to this amount, then slow down and start adding NaOH in drop-fashion. Considering that the NaOH should be within a few percent of 0.30 M, what volume (in mL) would you expect to use for your third trial with 0.7943 g of KHP? Round your answer to 2 sig figs. Record this volume on your Cover Page and refer to it when performing your titration in Part 1. N
