Questions and Answers

What is precipitation titremetry based on?

  • Reactions that yield ionic compounds that are purely organic
  • Reactions that yield ionic compounds of limited solubility (correct)
  • Reactions that yield ionic compounds that are gaseous
  • Reactions that yield ionic compounds of unlimited solubility
  • Why are only a few precipitating agents used in titrimetry?

  • Because of the toxic nature of most precipitating agents
  • Because of the slow rate of formation of most precipitates (correct)
  • Due to the unavailability of most precipitating agents
  • Due to the high cost of most precipitating agents
  • Which reagent is the most widely used in precipitation titremetry?

  • Calcium chloride
  • Silver nitrate (correct)

    Study Notes

    Precipitation Titremetry

    • Precipitation titremetry is based on reactions that form ionic compounds with limited solubility.

    Precipitating Reagents

    • Only a few precipitating agents can be used in titrimetry due to the slow rate of formation of most precipitates.
    • Silver nitrate is the most widely used and important precipitating reagent.

    Applications of Silver Nitrate

    • Silver nitrate is used for the determination of: • Halides • Halide-like anions (SCN-, CN-, CNO-) • Mercaptans • Fatty acids • Several divalent and trivalent inorganic anions
