The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Area of Science:

  • Analytical Chemistry
  • Electrochemistry
  • Inorganic Chemistry

Context:

  • Microanalysis of organic compounds requires precise and sensitive methods.
  • Existing methods for arsenic, antimony, and copper determination may lack accuracy or efficiency.
  • Electrochemical techniques offer potential for improved analytical performance.

Purpose:

  • To develop a novel microanalytical method for simultaneous determination of arsenic, antimony, and copper in organic matrices.
  • To establish a coulometric titration procedure utilizing electrogenerated iodine.
  • To validate the method's accuracy and precision using amperometric end-point detection.

Summary:

  • Organic compounds are decomposed using a mixture of sulfuric and nitric acids.
  • Arsenic and antimony are oxidized to arsenate (AsO4^3-) and antimonate (SbO4^3-) ions, respectively; copper is directly obtained as Cu^2+ ions.
