# A 4000mL aliquot of 00500 M HNO2 is diluted to 750 mL and titrated with 00800 M Ce4 Assume the hydrogen ion concentration is at 100 M throughout the titration Use 144 V for the formal

A 40.00-mL aliquot of 0.0500 M HNO2 is diluted to 75.0 mL and titrated with 0.0800 M Ce4+. Assume the hydrogen ion concentration is at 1.00 M throughout the titration. (Use 1.44 V for the formal potential of the cerium system.)

(a) Calculate the potential of the indicator electrode with respect to a AgCl (sat&#39;d) reference electrode after the addition of 5.00, 10.00. 1500. 20.00, 25.00, 40.00, 45.00, 49.00, 49.50, 49.60.49.70. 49.80. 49.90. 49.95, 49.99, 50.00, 50.01, 50.05, 50.10, 50.20, 50.30, 50.40, 50.50, 51.00, 55.00, 60.00, 75.00, and 90.00 mL of cerium (IV)

(b) Construct a titration curve for these data.

(c) Generate a first- and second-derivative curve for these data. 43 Does the volume at which the second-derivative curve crosses zero correspond to the theoretical equivalence point? Why or why not?
