- Why should we do a standardization every time we do a titration?This is about determinition of acid content in vinegar through titration, please answer the questions. Please answer only the items nummber 4-5. i only put other questions for guide. 1. What is the purpose of standardization? 2. What is the primary standard used (name and formula)? ANS: KHP 3. Suppose that the KHP is not completely dry. Will the reported molar concentration of the sodium hydroxide solution be higher, lower, or unaffected? Explain. 4. In preparing the buret for titration the final rinse is with the NaOH titrant rather than with distilled water. Explain. 5. The procedure suggests the addition of only 2 drops of phenolphthalein. What will be the effect to the analysis if larger amount of phenolphthalein is added?Thank 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…

- Hello! I have a question I'm confused about: "An air bubble of some size was present in the liquid in the buret at the end of the first titration but not at the beginning. What is the effect on the calculated concentration of NaOH - increase, decrease, or no change? Explain your answer." I know at the beggining of a titration if there is an air bubble in the burett, then that could cause the volume reading to be to high, but I'm not sure how concentration ties in, or if there is a difference in the fact the the air bubble was at the end of the titration. Could you offer some guidance? Thank you.Questions 11-14 refer to the same strong base/strong acid (SB/SA) titration. A 15.00 mL solution of 0.100 M sodium hydroxide (NaOH) is being titrated with 0.250 M hydrobromic acid (HBr). What is the total solution volume (in mL) at the equivalence point? (Nearest whole number) Type your answer...if the bubble in the tip of the buret is not removed prior to performing HCl titration will the reported concentration of the HCl be greater than, less than, or equal to the true concentration of the HCl if the bubble is pushed from the buret during the titration? (in respect to volumetric analysis)
