Mass of KHP 3.009 g 3.246 g Data: Table 2 Trial 1 Trial 2 2. Final Buret Reading 43.33 mL 47.13 mL 3. Initial Buret Reading .50 mL 1.20 mL 4. Volume of NaOH Used (in mL) 5. Volume of NaOH Used (in L) [convert from mL to L] Results: Table 3 Trial 1 Trial 2 6. # Moles of KHP Titrated 7. # Moles of NaOH Required to React with KHP 8. Concentration of NaOH Solution (in Molarity) 9. Average Concentration of NaOH Solution (in Molarity) Q1)Show how you calculated the number of moles of KHP (line 6.) titrated for both trials #1 and #2. Q2)Show how you calculated the number of moles of NaOH required to completely react with the moles of KHP (line7.) for both trials #1and2. Q3)Show how you calculated the concentration of the NaOH solution (line 8.) for both trials #1 and #2. Q4) In this experiment, why do you add phenolphthalein to the solution before the titration begins.
