- A student added 5.00 mL of vinegar instead of 10.00 mL to their titration flask. Will the titration require more, less, or the same amount of NaOH titrant to get to the endpoint? Briefly, 1 - 2 sentencesInstructions: Refer to the photo below. Answer the ff: c. At equivalence point d. Past the equivalence pointA student delivers several drops of titrant from their buret, but the drops land on the side of the Erlenmeyer flask. The student ultimately finishes the titration and the drops are still on the side of the flask. How is the % acetic in their determination affected by this error? Briefly, 1 - 2 sentences,
- The labels on most pharmaceuticals state that the medicine should be stored in a cool, dark place. In the context of this chapter, explain why this is sound advice.Hi, how would I know the half equivalence point and the equivalence point if you are shown a graph like this?Find moles of NaOH added and equivalence point
- please calculate the neutralization equivalent for each run for part II. and for part III, calculate the neutralization equivalent for malonic acid and maleic acidV. Error Analysis/Questions For the following questions explain what specific error in calculating your Ksp value would occur (i.e. would the Ksp be too HIGH or too LOW), compared to the situation in which no errors occur. When you answer the question, consider how the situation affects the calculation of Ksp. Each answer must have an explanation and type the answer, please. A. The buret was not conditioned (it still had water in it) when you add the HCl. Would the Ksp be too HIGH or too LOW? B. There was Ca(OH)2 solid (that was not filtered off) in your solution to be titrated. Would the Ksp be too HIGH or too LOW? C. You measured 24.00 mL of Ca(OH)2 solution instead of 25.00 mL. Would the Ksp be too HIGH or too LOW? D. The HCl concentration was actually lower than the reported molarity on the bottle. Would the Ksp be too HIGH or too LOW?Calculate the λmax for this compound.
- The color change at the endpoint should persist for 30 seconds. Explain why the time lapse is a good titration technique.what glassware should be used to add the sodium hydroxide into the hydrochloric acid solution? A. Volumetric pipette b. Graduated cylinder c.
