Test 5 Take Home Aqueous Equilibria 8. For the following titration curve pts Fill in the blanks in the title with appropriate terms regarding the strength and acid or base character of the analyte and titrant. a. Titration of 25.0 mL of with 0.10 M 12 10 25 30 35 40 45 50 10 15 20 Volume of 0.10 M added (mL) b. Determine the value of pKx of the analyte (I'm purposely "mislabeling" this pts. term to avoid giving away part of the answer in part a) Which indicator makes more sense to use for this titration, methyl red or phenolphthalein? Defend your choice with a logical explanation c. 2 pts. Pave 6 of 7

Explanation / Answer

Volume of 0.10M acid added (mL)

b. pKX= 5.75

c. Methyl red will be used as an indicator because it only can change color in this pH range.
