I have some of the analysis and evaluation questions below to hopefully simplify your write-ups. Please take note of the changes in bold. Lab Report: Acid-Base Titration Here is what is required for the lab write-up: 1) Title Page [1C] 2) Purpose [1C] Determine the concentration of an unknown acid by titrating it with an NaOH solution of known concentration. 3) Hypothesis [2T] It’s up to you to structure your hypothesis. Should be predictive and descriptive. Ideas: Hypothesis can be about accuracy of calculations, comparing strong and weak acids 4) Materials [2C] Make sure you write what you actually used, not what’s in the lab in the text. Below are the chemicals used:
5) Procedure [2C] Make sure you write what you actually did, not what’s in the lab in the text 6) Observations [6C] · Should be in the form of a table including initial volume of titrant, final volume of titrant and amount of titrant added for each trial (for your group only) · Include qualitative description of chemicals used and any other changes you observed during the lab 7) Analysis [10A] You will use the class data for the following. Show all work. State all assumptions you make in your calculations. a) calculate the average amount of titrant used for each sample solution b) calculate the number of moles of titrant used for each sample solution c) calculate the concentration of H+ ions and pH for each sample solution (perform calculations as if acetic acid is a strong acid) d) calculate the initial concentration of each sample solution [Edited] 8) Evaluation [10T] Answer the following questions in full sentences: a) Restate and compare the concentrations and pH of the HCl and H2SO4. Explain any differences or similarities. b) The acetic acid we used actually came from vinegar with a pH of approximately 2.4. Compare this value to the value you calculated in the analysis. Why is it so different? [Edited] c) Use the example above to describe the difference between strong and concentrated acids and bases. Why is it important to use the correct term when it comes to chemical safety? d) Discuss 3 sources of experimental error in this investigation. Be specific 9) Conclusion [10C] 10) 7 Professionalism Marks Friday, May 224.2 Spontaneity

Explain any differences or similarities. b) The acetic acid we used came from vinegar with an acetic acid molarity of approximately 0.87 mol/L. Compare this value to the concentrations of HCl and H2SO4 you calculated and how much titrant was added to reach the equivalence point. Explain the difference with your knowledge of strong and weak acids. c) Use the example above to describe the difference between strong and concentrated acids and bases. Why is it important to use the correct term when it comes to chemical safety? d) Discuss 3 sources of experimental error in this investigation. Be specific 9) Conclusion [10C] 10) 7 Professionalism Marks Friday, May 15Unit 3 Test Today! Good luck
