Question

At 25 °C, you conduct a titration of 15.00 mL of a 0.0460 M AgNO3 solution with a 0.0230 M NaI solution within the following cell: Saturated Calomel Electrode || Titration Solution | Ag (s)

For the cell as written, what is the voltage after the addition of the following volume of NaI solution? The reduction potential for the saturated calomel electrode is E = 0.241 V. The standard reduction potential for the reaction

Ag+ + e- --> Ag(s)

is E0 = 0.79993 V. The solubility constant of AgI is Ksp = 8.3 × 10-17.

a) 0.5 mL

b) 13.90 mL

c) 30 mL

d) 43.10 mL
