Jason and his friends wish to determine iron content in an industrial sludge sample. They have decided to carry out redox titration experiment. Given half reactions involved in this case as follow. Fe+ + e- Fe2+ E° = 0.77 V Ce* + e→ Ce+ E° = 1.70 V a) Construct a balanced chemical reaction for this case. b) Assess the E° for this reaction. c) Indicate whether there is a pH indicator that could be used to determine the endpoint of this titration. If yes, name the indicator that they would use. d) Suppose a 50 mL of 0.1 M Fe+ was titrated with 0.1 M Ce, calculate volume of Ce* required to reach equivalence point. e) Assume that the potential of titration is monitored against a platinum electrode, determine the potential they would measure upon addition of 15 mL titrant.

Jason and his friends wish to determine iron content in an industrial sludge sample. They have decided to carry out redox titration experiment. Given half reactions involved in this case as follow. Fe+ + e- Fe2+ E° = 0.77 V Cett+ e→ Ce³+ E° = 1.70 V a) Construct a balanced chemical reaction for this case. b) Assess the E° for this reaction. c) Indicate whether there is a pH indicator that could be used to determine the endpoint of this titration. If yes, name the indicator that they would use. d) Suppose a 50 mL of 0.1 M Fe+ was titrated with 0.1 M Ce*, calculate volume of Ce* required to reach equivalence point. e) Assume that the potential of titration is monitored against a platinum electrode, determine the potential they would measure upon addition of 15 mL titrant.
