QUESTIONS - Please tally using entire sentences and cares where delayhold.

  1. Why doesn't the KHP force bear to be exactly 0.100M?  Explain using entire sentences.
  2. Why is it relevant that you exactly know the force of KHP? Explain using entire sentences.
  3. Why can't you exactly know the force of NaOH by consideration some and adding impart?  Explain using entire sentences.
  4. Set up the care required to designate the force of the NaOH key via titration of a ardent whole of KHP. Include all total exclude the ardent body of KHP.
  5. Set up the care required to designate the force of the mysterious vigorous aculeated via titration delay a unreserved work of NaOH of unreserved force. Include all total exclude the work and force of NaOH.
  6. Set up the care required to designate the force of the mysterious ductile shameful via titration delay the mysterious vigorous aculeated of unreserved force and work. Include all total exclude the work and force of the mysterious aculeated.
  7. Error partition - EXPLAIN what issue each of the aftercited would bear on the development listed:
  • a. The pipet you used to gauge out precisely 25.00mL of KHP was rinsed singly in distilled impart but not rinsed in aculeated key. What is the issue on the fitted force of NaOH? (remember: force is a number - acception, decline, or no fluctuate). Explain your tally.
  • b. The beaker into which the 25.00mL of KHP was acquired was not dry. What is the issue on the fitted force of NaOH - acception, decline, or no fluctuate? Explain your tally.
  • c. An air toy of some bigness was bestow in the fluent in the buret at the end of the foremost titration but not at the initiation. What is the issue on the fitted force of NaOH - acception, decline, or no fluctuate? Explain your tally.
  • d. After you uprightly designate the force of NaOH, the NaOH is left known overnight, so that some CO2 is dissolved in it. What is the issue on the fitted force of vigorous aculeated - acception, decline, or no fluctuate? Explain your tally. Include a balanced chemical equation involving NaOH and CO2.
  • e. Why would it be OK to use phenolphthalein during the relieve titration, but not the foremost and the third?
  • f. Suppose the KHP is rotten and is singly 95% clean. What is the issue on the fitted force of the ductile shameful? Explain your tally.

8) What is the Kb of the mysterious shameful? Describe how you arrived at your tally.  Include cares. 

9) Using a chart of Kb, what is the mysterious ductile shameful?  (Kb consideration.png)
