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
  • Physical Chemistry

Context:

  • Dicarboxylic acids are important organic compounds with various industrial applications.
  • Accurate determination of acid dissociation enthalpies is crucial for understanding chemical behavior and reactions.

Purpose:

  • To develop and validate a thermometric titration method for the direct analysis of maleic, fumaric, tartaric, glutaric, and adipic acids.
  • To measure heats of neutralization and deduce enthalpies of dissociation for these acids.

Summary:

  • Five dicarboxylic acids were titrated with sodium hydroxide using an automatic thermometric titrimeter.
  • Titration curves revealed two distinct break-points, indicating sequential neutralization of acid groups.
  • The method allows for the determination of enthalpies of dissociation with a relative standard deviation of approximately 3% for 0.3–1 mmole of acid.
