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

Context:

  • Determination of manganese (Mn) and chromium (Cr) in organic matrices presents analytical challenges.
  • Existing methods may require complex sample preparation or lack precision.

Purpose:

  • To develop and validate a constant-current coulometric titration method for simultaneous determination of Mn and Cr in organic compounds.
  • To establish a precise and reliable analytical technique for trace element analysis.

Summary:

  • Organic compounds are decomposed using a mixture of sulfuric and nitric acids.
  • Manganese and chromium are oxidized to permanganate (MnO(4)(-)) and dichromate (Cr(2)O(7)(2-)) respectively.
  • Electrolytically generated Fe(2+) is used for titration with amperometric endpoint detection.
